      Dear colleagues!
      There are some interesting properties of two triangle centers.
      Let P1, P2 are the Brocard points of triangle ABC, C0 is the common point of
      AP1 and BP2, such that AC0=BC0, C1 is the reflection of C0 in AB, C2 is the
      common point of perpendiculars to AC0 from A and BC0 from B, A1, A2, B1, B2
      are defined similarly. Then the lines AA1, BB1, CC1 concur in X(262) and
      AA2, BB2, CC2 in X(83).

      Sincerely Alexey
