Abstract
We prove that the minimum number of Hamilton cycles in a Hamiltonian threshold graph of order (Formula presented.) is (Formula presented.) and this minimum number is attained uniquely by the graph with degree sequence (Formula presented.) of (Formula presented.) distinct degrees. This graph is also the unique graph of minimum size among all Hamiltonian threshold graphs of order (Formula presented.).
