We obtain the sufficient conditions for the integrality of the distance powers ᴦD of the Cayley graph ᴦ = X(D2n, S) (resp. ᴦ = X(D4n, S)) (n ≥ 3)) for a set of nonnegative integers D. In particular, for a prime p, we show that if ᴦ = X(D2p, S) (resp. ᴦ = X(D4p, S)) is integral, then the distance powers of ᴦ = X(D2p, S) (resp. ᴦ = X(D4p, S)) are integral Cayley graphs. |
