Question

show that following graph is isomorphic or not
​

Answer 1

Answer:

A good way to show that two graphs are isomorphic is to label the vertices of both graphs, using the same set labels for both graphs. ... In each case the degree sequence is (2,2, 2,3,3) so we might expect that there is an isomorphism. First we put labels “A” and “B” on the two degree-3 vertices..
