Aiello's Mural Style —
Cullinane's Abstract Style —
A Cayley superline of the Klein quadric in PG(5,2)
is actually a plane of the quadric. Any such plane can be
pictured as a set of seven partitions of an 8-set into four 2-sets,
with the partitions satisfying certain geometric conditions.
A prototypical example of such a set: the four-colored bricks
numbered 1 through 7 at left in the picture below.
