Conic locus of inversive Poncelet circumcenter and two points of invariant circle power

Authors: Ronaldo Garcia, Shmuel, Helman, Dan Reznik

We prove that over a generic Poncelet triangle family, the locus of the circumcenter of an inversive triangle is a conic. Additionally, we prove an earlier conjecture: over generic Poncelet triangles, two unique points exist which maintain constant power with respect to the circumcircle and Euler's circle of the family, respectively.
