HYACINTHOS 5423

• Dear Hyacinthos!
  A week ago I've found one property of 184-point in Clark List.
  That point generates three equil triangles, similar to the base triangle
  ABC, and "inscribed" in it.
  Please, see attachment.
  So, I suspect, that is the main geometry property of that point.
  But is this property well known?
  Yours,
  Alexei Myakishev
