... is the greatest common divisor of the degrees of H. Clearly, if the conditions in Wilson’s Theorem hold, then the packing and covering numbers are known. In this paper we solve all of the conjectures ... gcd(G), and h | m, then G has an H-decomposition. ✷ It is worth mentioning that N(H) in Gustavsson’s Theorem is a rather huge constant; in fact, it is a highly exponential function...
