Cosmin Pohoata, A note on the anticomplements of the Fermat points,
Forum Geometricorum, 9 (2009) 119--123.

Abstract: We show that each of the anticomplements of the Fermat points is common to a triad of circles involving the triangle of reflection. We also generate two new triangle centers as common points to two other triads of circles. Finally, we present several circles passing through these new centers and the anticomplements of the Fermat points.
