The domination number γ(Cm □ Pn) of the Cartesian product Cm □ Pn of a cycle and a path has been computed when m ≡ 0, 2 (mod 5). In the remaining cases m ≡ 1, 3, 4 (mod 5), exact formulae for γ(Cm □ Pn) have been determined when either n ≤ 22 or m ≤ 30. For the rest of the cases, only lower and uppe ...
