Let G1?G2 and G1xG2 be the coalescence and Cartesian product of two connected m-uniform hypergraphs G1 and G2 respectively. We will give explicit formulas for the stabilizing indices and cyclic indices of G1?G2 and G1xG2 in terms of those of G1 and G2 or the invariant divisors of their incidence matrices over Zm, respectively.
