. In the case of a square of four points (Pll, Pul, Plr, and Prr where u=upper, l=lower/left, r=right), you expect a line between Pll and Pul, you also expect a line between Pll and Plr. But a line between Pll and Prr is also valid.

No, that cannot happen. A square can only arise from a cross pattern of 5 dots. And a diagonal line connecting the opposite corners would pass through the central dot and could not be 'normal' to any divisor between that dot and any other.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
