Q179 is defined in page K018, see locus property 18. Recall that, for P on K018, the triangle whose vertices are the inverses of P in the circles with diameters BC, CA, AB is perspective to ABC at Q on Q179.

Q179 is a circum-quintic and A, B, C, G are nodes on the curve.

Q179 is tangent at G to the line {2, 538} and the contact G with this line is quintuple.

Q179 is tangent at A, B, C to the medians of ABC.
