Define the multi-family of sequences $$S(n,m,t)=sum_k_1+cdots+k_n=mbinommk_1,dots,k_n^t$$ where the sum runs over non-negative integers $k_1,dots,k_n$ . These numbers are related to average distances (from the origin) of uniform unit-step random walks on the plane. QUESTION. Is it always true that $n$ divides $S(n,m,t)$ ? Observe t...
