On Hamiltonian cycles in \(C_nX_{2:2}C_m\)
The directed graph \(C_nX_{2:2}C_m\) is obtained from the Cartesian product \(C_n \times C_m\) of two directed cycles \(C_n\) and \(C_m\) by adding new edges in a very special (artifical) way (to obtain a result). In the paper two sufficient conditions for the directed graph \(C_nX_{2:2}C_m\) to be Hamiltonian are proved.
