A finite fully invariant set of a continuous map of the interval induces a permutation of that invariant set. If the permutation is a cycle, it is called its orbit type. It is known that Misiurewicz-Nitecki orbit types of period $$n$$ congruent to $$1 \pmod 4$$ and their generalizations to orbit types of period $$n$$ congruent to $$3 \pmod 4$$ have maximum entropy amongst all orbit types of odd period $$n$$ and indeed amongst all $$n$$-permutations for $$n$$ odd. We construct a family of orbit types of period $$n$$ congruent to $$0\pmod 4$$ which attain maximum entropy amongst $$n$$-cycles.
