Notes¶
Let A', B', C' be the inverse-in-Brocard-circle of A, B, C. Let A″, B″, C″ be the inverse-in-circumcircle of the vertices of 1st Brocard triangle. The lines A'A″, B'B″, C'C″ concur in X574. (Randy Hutson, November 18, 2015)
Let X'Y'Z' be the circumcevian-inversion triangle of X6, as defined in the preamble just before X34864. The A-vertex of this triangle is given by
X' = (2 a^2 - b^2 - c^2) (4 a^2 + b^2 + c^2) : b^2 (-2 a^2 + b^2 - 2 c^2) (5 a^2 + 2 b^2 + 2 c^2) : c^2 (-2 a^2 - 2 b^2 + c^2) (5 a^2 + 2 b^2 + 2 c^2).
The triangles ABC and X'Y'Z' are perspective, and their perspector is X574. (Peter Moses, December 9, 2019)
Let P1' be the tangent, other than U(1), to the Brocard circle from P(2). Let U1' be the tangent, other than P(1), to the Brocard circle from U(2). P1' and U1' are also the Schoute-circle-inverses of P(1) and U(1), resp. Then X574 = P(1)U1'∩U(1)P1'. (Randy Hutson, January 17, 2020)
