X(4), X(67), X(136), X(1263), X(1560), X(2079), X(3563), X(5504), X(14984) X(14984) = infinite point of X(3)X(895) and X(6)X(1511) X(3563) = X(2)X(136) /\ X(4)X(99) on the circumcircle 

K480 is a circular cubic related to CL051. The singular focus is X(5) which is the point of concurrence of the three asymptotes. It follows that the polar conic of X(5) must decompose into the line at infinity and the harmonic polar of X(5). The real asymptote is the parallel at X(5) to the lines X(3)X(895) and X(6)X(1511).
