X(3), X(6), X(22), X(3167), X(12163)

P = X(33878) = X(3)X(6) /\ X(22)X(3167)

vertices of these triangles :

• Thomson (points Qi)

• tangential of Thomson (points Ri)

Geometric properties :

K1120 is a member of the pencil of cubics generated by K172 and K1114. This is studied in Table 71.

K1120 meets the circumcircle again at three (not always all real) points which are the antipodes of the common points (apart A, B, C) of K006 and (O).
