A finite group $G$ is simple if it has only two normal subgroups - the trivial group and $G$ itself. Simple groups are building blocks for all finite groups, via extensions, and they are divided into cyclic groups of prime order and the non-abelian simple groups. For small orders they are all alternating or linear.
