Comments

Besides 3 for the cycle (5,7,6) the following lengths of cycles with elements <= 1500000 occur: 2, 4, 6, 10, 12, 16, 18. The even period lengths appear in a rather regular manner, presumably infinitely often.

Examples

			A114727(12) = 32 belongs to the 6-cycle (32,37,36,35,34,33), so a(12) = 6.
