Let 0<α1<⋯<αkbe integers and [Formula: see text] , ak≠0. Define [Formula: see text] where m|n and [Formula: see text] . We establish a relation among S(f,n) for all n with the same 2-adic order. When ν2(α1)=⋯=ν2(αk), where ν2is the 2-adic order function, we are able to compute S(f,n) explicitly for all n with a given f. Moreover, we are able to compute [Formula: see text] explicitly for all α>0, [Formula: see text] , m|n and [Formula: see text] .
