Then $H$ is a subgroup of $G$. +2 08:33 accept Suppose that $G$ is a group and $H$ a nonempty finite sub- set of $G$ closed under the product in $G$. Then $H$ is a subgroup of $G$.

 +10 14:17 upvote Prove $H\circ N = H\cap N$. Where $H$ and $N$ are two subgroups of a group $G$. +5 14:18 upvote Prove $H\circ N = H\cap N$. Where $H$ and $N$ are two subgroups of a group $G$. +2 06:25 accept First Isomorphism Theorem: Let $\phi : G\rightarrow G'$ be a homomorphism of groups. Then $G/\ker(\phi ) \cong \phi (G)$. +2 04:30 accept Let G be a group, and $N\triangleleft G$. Then, the quotient map $q: G\rightarrow G/N$ given by $q(g) = g\circ N$ is an epimorphism.
