Geometric properties :

K985 is the isogonal transform of K432, also the X(31)-isoconjugate of

It is a cubic anharmonically equivalent to K020 as in Table 66..

It is also the barycentric products X(1) x K738, X(6) x K1023, X(75) x K128. In other words, the barycentric equation given above is the trilinear equation of K128.
