Symplectic Structure…
In the Miracle Octad Generator (MOG):
The above details from a one-page note of April 26, 1986, refer to the
Miracle Octad Generator of R. T. Curtis, as it was published in 1976:
From R. T. Curtis (1976). A new combinatorial approach to M24,
Mathematical Proceedings of the Cambridge Philosophical Society ,
79, pp 25-42. doi:10.1017/S0305004100052075.
The 1986 note assumed that the reader would be able to supply, from the
MOG itself, the missing top row of each heavy brick.
Note that the interchange of the two squares in the top row of each
heavy brick induces the diamond-theorem correlation.
Note also that the 20 pictured 3-subsets of a 6-set in the 1986 note
occur as paired complements in two pictures, each showing 10 of the
3-subsets.
This pair of pictures corresponds to the 20 Rosenhain tetrads among
the 35 lines of PG(3,2), while the picture showing the 2-subsets
corresponds to the 15 Göpel tetrads among the 35 lines.
See Rosenhain and Göpel tetrads in PG(3,2). Some further background:

Space Case
"And there we were all in one place,
A generation lost in space…"
— Don McLean, "American Pie"
Today's NY Times says Robert T. McCall, space artist, died at 90 on Feb. 26.
"His most famous image may be the gargantuan mural, showing events from the creation of the universe to men walking on the Moon, on the south lobby wall of the National Air and Space Museum on the National Mall in Washington. More than 10 million people a year pass it.
Or it might be his painting showing a space vehicle darting from the bay of a wheel-shaped space station, which was used in a poster for Stanley Kubrick’s landmark 1968 film, '2001: A Space Odyssey.'"

Twanged!
 |
The Father of Rock and Roll,
music legend Sam Phillips,
died in a Memphis hospital
Wednesday night.
See also my entry Wednesday morning
on rock and roll, country music,
the Stones, and The Last Picture Show.
Meditation for this, the feast day of the founder of the Society of Jesus:
“If there’s a rock and roll heaven,
Well you know they’ve got
a hell of a band.”
