Anti-holomorphic iteration z ← conj(z)² + c. The boundary has three-fold symmetry instead of the Mandelbrot’s reflection symmetry.

Iteration rule

z_{n+1} = conj(z_n)² + c    with    z_0 = 0
expanded (z = x + iy, conj(z) = x − iy):
  Re z_{n+1} = x² − y² + Re c
  Im z_{n+1} = −2 x y + Im c
escape test: stop when |z_n| > 2

Anti-holomorphic (uses the complex conjugate), giving three-fold symmetry instead of reflection symmetry.
