# Pre-Periodic Point

Robert P. Munafo, 2002 May 27.

A pre-periodic iterate is a value of Z that is in the limit cycle for the value of c being iterated. Given the recurrence relation:

Z_{i+1} = Z_{i}^{2} + c

if the iteration has period n, then Z_{0} is pre-periodic
if and only if:

Z_{0} = Z_{n}
