A connected graph G is primitive provided there exists a positive integer k such that for each pair of vertices u and v in G there is a walk of length k connecting u and v. The smallest of such positi...

In [3], Orin Chein defined and constructed a class of Moufang loops called the M(G, 2) with a product rule which is rather complicated. We provide an alternative definition ofM(G, 2) with a much simpl...
