I wouldn't bet on either, to be honest. But thank you 😅

Maybe the original maximizes the number of line crossings...

The most proper way of communicating this truth is the simple equation
(20+25)²=2025
...

Yes, I see what you're getting at, guess I misunderstood the question a bit. "Ordered pairs of vertices" is the math / graph-theory language for the unit of analysis, as jimi writes. I tend to think of multiple such attributes as a vector-valued tie variable.

In the book I'm writing with Tom Snijders, we call them "tie variables", those n×(n-1) directed entities x_{ij} we usually analyse.
