K156 is the member of the Euler pencil of isogonal pK whose pivot is P = X(5059) such that OP = 5 OH (vectors). See Table 27. It has only one real asymptote which is parallel to that of the Soddy cubic K032. K032 and K156 generate a pencil of cubics that contains the union of the line at infinity and the Kiepert hyperbola.
