#cycle-crossover

Cycle crossover (CX) is applied to $P_1 = (2, 7, 8, 4, 6, 3, 1, 5)$ and $P_2 = (1, 4, 7, 8, 6, 2, 3, 5)$. The positions are split into cycles (start at position 1, look up the value of $P_2$ there, find that value's position in $P_1$, and repeat until back at the start). Child $C_1$ takes the first cycle from $P_1$, the second from $P_2$, the third from $P_1$, and so on. What is $C_1$?
