  2. A3B3C3 is also cyclologic to ABC. Cyclology center lies on circumcircle of A3B3C3.

  3. P=x(32) then Q=(a^2 (a - b) (a + b) (a - c) (a + c) (a^2 b^2 - a^2 c^2 -
    b^2 c^2) (a^2 b^2 - a^2 c^2 + b^2 c^2) (b^6 + a^4 c^2 +
    a^2 c^4) (a^4 b^2 + a^2 b^4 + c^6):.... :....)

  4. P=(a^3:b^3:c^3 ) then Q=(a^2 (a - b) (a + b) (a - c) (a + c) (a^2 b^2 - a^2 c^2 -
    b^2 c^2) (a^2 b^2 - a^2 c^2 + b^2 c^2) (b^6 + a^4 c^2 +
    a^2 c^4) (a^4 b^2 + a^2 b^4 + c^6):....:....)
