**Alexei Myakishev and Peter Woo, On the circumcenters
of cevasix configurations,**

Forum Geometricorum 3 (2003) 57--63.

**Abstract:** We strengthen Floor van Lamoen's theorem
that the 6 circumcenters of the cevasix configuration of the centroid of
a triangle are concyclic by giving a proof which at the same time shows that
the converse is also true with a minor qualification, *i.e.*,
the circumcenters of the cevasix configuration of a point P are concyclic
if and only if P is the centroid or the orthocenter of

the triangle.
