WebWe note that there are 6 odd degrees and 0 is even, thus it is possible that a simple graph will exist with the degree sequence. The graph should have 6 vertices, because the sequence contains 6 numbers. Each vertex then needs to have degree 1, which results in a possible simple graph and thus the sequence is graphic \textbf{graphic} graphic. kfc blackburn the mall https://xquisitemas.com
