A Perfect One-Factorisation of $K_{56}$

Combinatorics 2019-02-05 v2

Abstract

In 1963, Anton Kotzig conjectured that for each n2n \geq 2 the complete graph K2nK_{2n} has a perfect one-factorisation (i.e., a decomposition into perfect matchings such that each pair of perfect matchings of the decomposition induces a Hamilton cycle). We affirmatively settle the smallest unresolved case for this conjecture.
