Jul 11, 2021 at 7:01 | comment | added | Wlod AA | Let $\ n>2\ $ be a prime number. Let the vertices form a regular n-gon. There are $\ a:=\frac{n-1}2\ $ Hamiltonian cycles, one for each length of the edges. Then there are $\ \binom a2\ $ (unordered) pairs of these cycles where the members of the same pair are edge-disjoint. | |
