      Let ABC be a triangle and A'B'C' the cevian / pedal
      triangle of a point P.

      Denote:
      Ab, Ac:=The orthogonal projections of B',C' on PC',PB',
      resp.

      A":= B'C' /\ AbAc.

      Similarly Bc,Ba, B" and Ca,Cb, C".

      Which is the locus of P such that:

      1. AbAc, BcBa, CaCb are concurrent

      2. A",B",C" are collinear.
