Planar hypohamiltonian oriented graphs

In 1978 Thomassen asked whether planar hypohamiltonian oriented graphs exist. Infinite families of such graphs have since been described but for infinitely many n it remained an open question whether planar hypohamiltonian oriented graphs of order n exist. In this paper we develop new methods for co...
