State the necessary conditions for two graphs to be isomorphic. How many different words from 'MANAGER' can be generated with or without meaning? [5]

Two graphs $G1 = (V1, E1)$ and $G2 = (V2, E2)$ are isomorphic if there exists a bijection (one-to-one and onto mapping) $f: V1 \to V2$ such that any two vertices $u$ and $v$ are adjacent in $G1$ if and only if $f(u)$ and $f(v)$ are adjacent in $G2$ . For two graphs to be isomorphic, the following ...
