AI Thread Summary
To determine if two graphs are isomorphic, one must first understand the definition of graph isomorphism, which involves a one-to-one correspondence between their vertex sets that preserves adjacency. The discussion emphasizes the importance of providing the specific graphs in question for analysis. Steps to check for isomorphism typically include comparing the number of vertices and edges, examining degree sequences, and potentially using algorithms or software tools for more complex graphs. The user is encouraged to share the graph images for a more detailed evaluation. Understanding these concepts is crucial for accurately assessing graph isomorphism.

how can i determine if the graph isomorphic

is there is steps to do that

thanx

First, tell us what the graph is!

Second, what is the definition of "isomorphism" for graphs?
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
