The previous post suggests a flashback to June 8, 2014 —

In the simplest case of a projective space
(as opposed to a plane ),
there are 15 points and 35 lines:
15 Göpel lines and 20 Rosenhain lines.*
The theorem of Desargues in this simplest case
is essentially a symmetry
within the set of 20 Rosenhain lines.
The symmetry, a reflection about the main diagonal
in the square model of this space, interchanges
10 horizontally oriented (row-based) lines with
10 corresponding vertically oriented (column-based) lines.

Vide Classical Geometry in Light of Galois Geometry.

* The two types of lines named are derived from
a natural symplectic polarity in the space.
The square model of the space, apparently first described
in notes written in October and December, 1978,
makes this polarity clearly visible:
