Notes

Let P and Q be the intersections of line BC and circle {X3,2R}. Let A' be the circumcenter of triangle PQX3, and define B' and C' cyclically. The lines AA', BB', CC' concur in X3257. (Randy Hutson, December 26, 2015)

Let A'B'C' and A″B″C″ be the Ursa-minor and Ursa-major triangles, resp. Let A* be the reflection of A' in line B″C″, and define B* and C* cyclically. Let A** be the reflection of A″ in line B'C', and define B** and C** cyclically. Let A# = B*B**/\ C*C**, and define B# and C# cyclically. The lines AA#, BB#, CC# concur in X3257.
