This post continues a post from yesterday on the square model of

PG(3,2) that apparently first appeared (presented as such*) in . . .

Cullinane, "Symmetry invariance in a diamond ring,"

*Notices of the AMS *, pp. A193-194, Feb. 1979.

Yesterday's Wikipedia presentation of the square model was today

revised by yet another anonymous author —

Revision history accounting for the above change from yesterday —

The jargon "rm OR" means "remove original research."

The added verbiage about block designs is a smokescreen having

nothing to do with the subject, which is *square* representation

of the 35 points and lines.

* The 35 squares, each consisting of four 4-element subsets, appeared earlier

in the Miracle Octad Generator (MOG) of R. T. Curtis (published in 1976).

They were not *at that time* presented as constituting a finite geometry,

either affine (AG(4,2)) or projective (PG(3,2)).
