The answer to Woodall's musquash problem (Q1817562)

An \(n\)-gonal musquash is a planar drawing of an \(n\)-gon, \(n \geq 5\), in which each pair of edges meets precisely once and the intersection has cyclic symmetry. It was known that \(n\)-gonal musquashes exist for \(n\) odd and for \(n=6\) and do not exist for \(n\) a multiple of 4. In the paper under review, the authors complete the solution of the existence problem by proving that there exist no \(n\)-gonal musquashes for \(n=2m\), \(m\) odd.
