Fundamental homomorphism theorem (FHT)
If : G→ H is a homomorphism, then Im(#) G/Ker().
The FHT says that every homomorphism can be decomposed into two steps: (i) quotient
out by the kernel, and then (ii) relabel the nodes via .
Let G be a finite group and N a normal subgroup of G. Prove that the order of the quotient
group G/N is given by the index of N in G, i.e.,
