Question: If the question is about proving $$P$$, which, pointed out in comments, follows from $$Q$$ and $$R$$. Is it acceptable to write an answer only containing the proof of $$Q$$, as part of collaboration?
• $$Q$$: It has girth 5, and
• $$R$$: It has unbounded chromatic number.
I can prove the graph has girth 5 with high probablity under my model, but I'm not sure whether they have unbounded chromatic number. Maybe someone can prove $$R$$, and it would complete the answer.
• @GerhardPaseman Suppose there is an answer for $Q$ and another answer for $R$. Which answer should be accepted? Or maybe they should be written in a single answer? – LeechLattice Aug 17 at 17:25
