Conjugate Subgroup

  • Definition: A subgroup H of an original group G has elements h_i. Let x be a fixed element of the original group G which is not a member of H. Then the transformation x(h_i)x^(-1), (i=1, 2, ...) generates the so-called conjugate subgroup xHx^(-1). If, for all x, xHx^(-1)=H, then H is a normal (also called "self-conjugate" or "invariant") subgroup.
