Its formula: x = Z.real; y = Z.imag; Znew.real = 6 * P1.real * x * y * y - x * x * x + P1.real + 0.6; Znew.imag = y * y * y - 6 * P2.imag * x * x * y + P1.imag - 0.5; where: P1.real = 0.5; P1.imag = 0.5; P2.real = 0.527363184079602; P2.imag = 0.507462686567164; with filter "Orbit Counting IV", filter limit - 0.05.        Image Copyright © 1999 Arthur Sirotinsky
