For the complete graph $K_4$ as a strongly regular graph, what should he parameter $\mu$ be? Due to K4 is complete so it has no non-adjacent vertices, Mathworld gave its $\mu=0$,but is $\mu=2$ also allowed in such special case? http://mathworld.wolfram.com/TetrahedralGraph.html

    wouldn't that be any number since there's no non-adjacent vertices?2012-05-24

    I'd recommend including a definition of $\mu$ in the body of the question.2012-05-24

    Please post the second question separately. Questions can include subquestions that are aspects of the same problem, but asking two completely separate questions in one post makes search and tagging more difficult, mixes up answers to different things and forces people to read about both things when they're only interested in one of them.2012-05-24

    Are you aware that you can edit your question? You posted the second part as a separate question (as I'd suggested) but failed to remove it here; that's potentially very wasteful as people providing answers to the two questions may not be aware of the effort already invested in the other version. I removed that part.2012-05-25
