s = 3.1. The 2-cycle is stable. Note the alternating pattern of black and brown boxes. s = 3.5. What do you see? Often the first answer is a 3-cycle, because there are three colors: green, brown, and black. However, it is not the number of colors, so much as the order of colors that is important. Note the pattern: green, brown, black, brown, then repeat. The repeating pattern is of length four, and indeed the s = 3.5 logistic map has a 4-cycle.
