"WebbWe will prove that G has a Hamiltonian path by using the following theorem, known as Dirac's theorem: Dirac's Theorem: Let G be a simple graph with n vertices, where n>=3. If every vertex in G has degree at least n/2, then G has a Hamiltonian cycle. In our case, G has 2k+1 vertices, so n=2k+1. Since G is k-regular, each vertex in G has degree k.
