Generated subgroup
WebIf G is a group and g is an element oΥf G, the subgroup generated by g (or the cyclic subgroup generated by g) is hgi = {gk k∈ Z}. In other words, hgi consists of all (positive or negative) powersof g. This definition assumes multiplicativenotation; if the operation is addition, the definition reads WebOct 3, 2011 · 1. Oct 2, 2011. #1. Problem: Find all subgroups of Z 18, draw the subgroup diagram. Corollary: If a is a generator of a finite cyclic group G of order n, then the other generators G are the elements of the form a r, where r is relatively prime to n. I'm following this problem in the book.
