What is point graph?
The point graph of a $$pg(s,t,\alpha)$$ is a strongly regular graph: $$srg((s+1)\frac{(s t+\alpha)}{\alpha},s(t+1),s-1+t(\alpha-1),\alpha(t+1))$$.

What means point graph here? It needs explanation, link to article or reference to article/book. Jumpow (talk) 16:26, 21 August 2017 (UTC)

Is it collinearity graph? Jumpow (talk) 16:40, 21 August 2017 (UTC)
