Consider a triple {x,y,z} of real (or sometimes complex) numbers and define the point F(x,y,z) = S / √3 x X(6) + 2y X(4) + z X(3) where S = 2 area(ABC). Obviously, F(1,0,0)= X(6), F(0,1,0) = X(4), F(0,0,1) = X(3) and also F(0,1,2) = X(2), F(0,1,1) = X(5), F(3,2,1) = X(13), F(√3,0,1) = X(371), etc. Conversely, if X(n) is a center such that there exists a triple such that F(x,y,z) = X(n), then X(n) will be said to be a KHO-center and {x,y,z} will be called its KHO-coordinates. Now, let P(x,y,z) = 0 be a homogeneous polynomial equation of degree n with constant coefficients, and let C(x,y,z) = 0 be the curve (of same degree) that is the locus of the corresponding points F(x,y,z). P(x,y,z) = 0 is then called the KHO-equation of C. Conversely, if a curve has a barycentric equation that can be associated to some KHO-equation, then C will be said to be a KHO-curve. Examples : • The Euler line, Brocard axis, van Aubel line, Fermat axis, Napoleon axis are KHO-lines with KHO-equations x = 0, y = 0, z = 0, y - 2z = 0, 3y - 2z = 0 respectively. • The Kiepert hyperbola and the Evans conic are KHO-conics with KHO-equations x^2 - 3z (2y - z) = 0 and x^2 - 2 y^2 - (y - z)^2 = 0 respectively. • K369 and K458 are two nodal KHO-cubics with KHO-equations x^2 (2y + z) - 3 (2y - z) (y + z)^2 = 0 and x^2 (2y - 3 z) - 3 (y - z)^2 (2y - z) = 0 respectively. • K1191, K1192, K1193, K1194 are other KHO-cubics. See analogous cubics in the tables below. • Q073, Q167, Q168, Q183 are examples of KHO-quartics.   Most of the time, KHO-equations are far more simple than the corresponding barycentric equations.
 KHO-equations of the form : x^2 (v y + w z) - (2y - z)(p y^2 + q z^2 + r y z) = 0 Here, v, w, p, q r are five real numbers and • v y + w z = 0 is the KHO-equation of a line L0 passing through K = X(6). • 2y - z = 0 is the KHO-equation of the line GK. • p y^2 + q z^2 + r y z = 0 is the KHO-equation of a pair of lines L1, L2, passing through K, which can be real and distinct, coincidental, imaginary depending on whether ∆ = r^2 - 4 p q is positive, null, negative. The corresponding cubic (K) has the following properties. • (K) passes through K which is a point of inflexion. The inflexional tangent is L0 and the harmonic polar is the Euler line. • (K) passes through G and meets the Euler line again at two points E1, E2 which lie on L1, L2. The nature of these two points depends on ∆.. The tangents to (K) at the three points pass through K. • When L1 = L2 ≠ L0, (K) has a node on the Euler line . See K369 and K458 for instance. • When L1 = L0 ≠ L2, (K) has a node at G. • When L1 = L2 = GK ≠ L0, (K) has a cusp at G with cuspidal tangent the Euler line. See K1195 and Table 3 below for other examples. The following table shows a selection of cubics of this type (with contributions by Peter Moses). G and K on the cubic are not repeated. The coloured cells correspond to certain types of cubics detailed below. The yellow lines are those for the Evans cubics passing through G and K. Other Evans cubics below. The grey lines are those containing the pivotal KHO-cubics described in page K1191.

 Other Evans KHO-cubics These are the cubics passing through X(13), X(14), X(15), X(16), X(17), X(18).

Another way to write the KHO-equation of these cubics is : (1 - T) (2 x - 3 y) (x + z) (x + 2 y - z) + T (2 x + 3 y) (x - z) (x - 2 y + z) = 0, where the left-hand product is the union of the lines {2,14,15}, {3,13,17}, {4,16,18}, and the right-hand product is the union of the lines {2,13,16}, {3,14,18}, {4,15,17}. Recall that X(3) is a point of inflexion and that the tangentials of X(2), X(4) are collinear with X(3) and lie on the Napoleon line and Fermat axis respectively.

 Cullen cubics : KHO-equations of the form : x^2 (v y + w z) - 3 (2y - z)(y + z)^2 = 0 See pink cells in the table above. Here, v, w are two distinct real numbers such that v + 2w ≠ 0. Every Cullen cubic (K) passes through G, K (which is a point of inflexion) and has a node at infinity, namely the infinite point X(30) of the Euler line. The polar conic (C) of X(30) has KHO-equation : (v - w) x^2 -9 (y + z)^2 = 0 showing that (K) is acnodal when v < w and crunodal when v > w. In this latter case, (K) has two real parallel asymptotes. See K369 and K1197. (C) meets the lines OK and HK at two pairs of points having KHO-coordinates (±3, 0, √(v-w)) and (±3, √(v-w), 0) respectively. These points are real when (K) is crunodal. The Hessian (H) of (K) has KHO-equation : (v - w) x^2 (2 w y + (v + w) z) + 9 (v y+w z) (y + z)^2 = 0. (K) and (H) meet at K, X(30) which is sextuple, and two other points of inflexion F1, F2 on the line with KHO-equation : (3v - 2w) y - (v -2w) z = 0. Their KHO-coordinates are (± 4√3 √(w - v), v - 2w, 3v - 2w) hence they are real when (K) is acnodal. For instance, with v = 2, w = 5, (K) is the acnodal cubic K1198 and F1, F2 are X(13), X(14). The polar conic of K splits into the tangent at K with equation v y + w z = 0 and the harmonic polar which is the Euler line. The polar conics of F1, F2 split into the respective tangents which meet at (0, 3 v - 2 w, 5 v - 6 w) on the Euler line and the harmonic polars which are parallel to the Euler line. Additional cubics computed by Peter Moses in Table 1 below.
 KHO-equations of the form : x^2 (v y + w z) - 3 (2y - z)(y - z)^2 = 0 See green cells in the table above. Here, v, w are two real numbers such that v + w ≠ 0 and v + 2w ≠ 0. Every cubic (K) passes through G, K (which is a point of inflexion) and has a node at the nine-point center X(5) of the Euler line. The polar conic (C) of X(5) has KHO-equation : (v + w) x^2 -3 (y - z)^2 = 0 showing that (K) is acnodal when v + w < 0 and crunodal when v + w > 0. In this latter case, (K) has two real parallel asymptotes. (C) meets the line GK at two points having KHO-coordinates (±3, 0, √(v+w)). These points are real when (K) is crunodal. The Hessian (H) of (K) has KHO-equation : (v + w) x^2 [2 (2v + 3w) y - (3v + 5w) z] - 3 (v y+w z) (y - z)^2 = 0. (K) and (H) meet at K, X(5) which is sextuple, and two other points of inflexion F1, F2 on the line with KHO-equation : (7v + 6w) y - (3v +2w) z = 0. Their KHO-coordinates are (± 4 √(- w - v), 3v + 2w, 7v + 6w) hence they are real when (K) is acnodal. The polar conic of K splits into the tangent at K with equation v y + w z = 0 and the harmonic polar which is the Euler line. The polar conics of F1, F2 split into the respective tangents which meet at (0, 9v + 10w, 17v + 18w) on the Euler line and the harmonic polars which pass through X(5) and meet the line GK at (±3, √(- w - v), √(- w - v)). For instance, with v = 2, w = -3, (K) is the acnodal cubic K458 and F1, F2 are X(15), X(16). Additional cubics computed by Peter Moses in Table 2 below.
