A subgroup H of the group G is a normal subgroup if g -1 H g = H for all g ∈ G. If H < K and K < G, then H < G (subgroup transitivity). if H and K are subgroups of a group G then H ∩ K is also a subgroup. if H and K are subgroups of a group G then H ∪ K is may or maynot be a subgroup.

WebHow do you show that Z = {0,1,2,3,4,5,6} under multiplication forms a group? Two points: That would need to be multiplication modulo 7 (to achieve closure). You also need to exclude the 0, which has no multiplicative inverse. Aside from that, you should draw up the group (multiplication) table, with entries 1–6 marking the rows and columns.
