Bernard Gibert, Antiorthocorrespondents of circumconics,
Forum Geometricorum, 3 (2003) 231--249.

Abstract: This note is a complement to our previous paper Orthocorrespondence and Pivotal Cubics. We study how circumconics are transformed under antiorthocorrespondence. This leads us to consider a pencil of pivotal circular cubics which contains in particular the Neuberg cubic of the orthic triangle.
