Abstract :
If r⩾1, and m0, m1, and m2 are each a multiple of (r+1)3+r3, then each isomorphic component of the graph C(m0)×C(m1)×C(m2) permits a vertex partition into (r+1)3+r3 perfect r-dominating sets. The result induces a dense packing of C(m0)×C(m1)×C(m2) by means of vertex-disjoint subgraphs, each isomorphic to a connected component of P2r+1×P2r+1×P2r+1. Additional results include a general lower bound on r-domination number of a Kronecker product of finitely many cycles. Areas of applications include efficient resource placement in communication networks and error-correcting codes
