Bijective proof for a partition identity
Here is another proof of your lemma: $\prod_{i=0}^\infty \frac{1}{1+x^{2^i}} = \prod_{i=0}^\infty \frac{1-x^{2^i}}{1-x^{2^{i+1}}} = 1-x$.

This is essentially the same proof as Sean Eberhard's.

An attempt to find expected value of clique number of special random graph
The estimates are pretty good, the error is $O(1)$ or perhaps even smaller. Asking for more is too much to hope for.

Your random graph is not special at all. It's the standard $G(n,p)$ model. You can find the answer in textbooks.
