The DrozFarny quintic Q044 is the locus of P such that the trilinear polar of P and the DrozFarny axis of P are parallel. See CL039. Q044 is an antigonal circular quintic with three real asymptotes parallel at G to those of the Thomson cubic K002. The two other imaginary asymptotes intersect at X(381), the midpoint of GH. Q044 has four nodes A, B, C, H. The nodal tangents at A are the symmedian AK and the line GbGc. The nodal tangents at H are parallel to the asymptotes of the Jerabek hyperbola. The tangents at Ha, Hb, Hc concur at G. The tangents at Ga, Gb, Gc concur at X(315). The tangent at G is the line X(2)X(99)X(671). Q044 is the locus of point Q such that Q, its antigonal and G are collinear.
