The Pelletier strophoid K040 and K806 generate a pencil of circular circum-cubics that contains the three pKs K949, K950, K951. The singular focus of K949 is the midpoint X(15746) of X(1), X(2291). K949 passes through : • Q1 = X(15727) = X(7) / X(1156) = X(7)-Ceva conjugate of X(1156), • Q2 = X(15728) = X(10427)* = X(6610)-isoconjugate of X(10427), on the circumcircle, • Q3 = X(15729) = Q1*, • Q4 = X(15730) = X(7) / X(1155), • Q5 = Q4*, • Q6 = X(7) / Q5. Most of these points lie on several simple lines. |
