Scholium ( Blue diamond ex cathedra )
For a transformation of these four diamonds and four squares to the
four columns and four rows of a square array, see a March 24 post.

"Meanwhile, back in 1937 . . ." — Weyl in Vienna.
That title was suggested by an artist wielding her art like a shield
in this morning's post "Art Process," and by the four squares and
four diamonds of yesterday's post "A Combinatorial Configuration."

For a related combinatorial configuration, take Oxbury's "16 lines"
to be the the 16 dots above and take the "8 points of intersection"
to be the four squares
234, 1234, 124, 24
23, 123, 12, 2
3, 13, 1, 0
34, 134, 14, 4
along with the four diamonds
234, 23, 3, 34
1234, 123, 13, 134
124, 12, 1, 14
24, 2, 0, 4.
Then each "line" is on two "points" and each "point" on
four "lines."
Note that these eight "points" — the four squares and the four diamonds
of Coxeter's figure — form the rows and columns of the following matrix:
| 234 | 1234 | 124 | 24 |
| 23 | 123 | 12 | 2 |
| 3 | 13 | 1 | 0 |
| 34 | 134 | 14 | 4 |

A rather different planes solution from Log24 on March 7 —
See the illustrations in this journal on that date and . . .
"Note that in the Design Cube image above, the six faces are viewed
as suspended in space on three pairs of parallel planes, with the observer
viewing the parallel images only from the three directions front to back,
right to left, and top to bottom. In the WebSim row of six faces, the images
are pictured as they might be seen by an observer whose viewpoints vary
as he himself floats in space around the cube."
