WebPatrick Corn contributed. In group theory, a semidirect product is a generalization of the direct product which expresses a group as a product of subgroups. There are two ways to think of the construction. One is intrinsic: the condition that a given group G G is a semidirect product of two given subgroups N N and H H is equivalent to some ...
