Eddington Elegy
The properties of the mathematical structures in yesterday's post
"Philosophy for Eddington" are those of the Dirac matrices discussed
by Arfken. An elegy for Arfken —

Sextet Space
“Perhaps the philosophically most relevant feature of modern science
is the emergence of abstract symbolic structures as the hard core
of objectivity behind— as Eddington puts it— the colorful tale of
the subjective storyteller mind.”
— Hermann Weyl, Philosophy of Mathematics and
Natural Science , Princeton, 1949, p. 237
Melissa C. Wong, illustration for "Atlas to the Text,"
by Nicholas T. Rinehart:
The above fanciful illustration pictures 6*9=54 colored squares on the six
faces of a 3x3x3 cube.
Compare and contrast the Aitchison labeling, not unlike the one above,
of 6*4=24 unit squares (or, equivalently, 24 pips at the squares' centers)
on a 2x2x2 cube.
Now consider how the 8-square "brick" of R. T. Curtis may be colored with
four colors using the 105 ways to partition its eight squares into four 2-sets.
By analogy, the 24 squares on a cube's surface, as above, afford a cubical
space for applying six colors to the sextet partitions (into six 4-sets) of Curtis's
Miracle Octad Generator (MOG), using Aitchson's cubical model (with, of course,
the parts to be moved being pips or squares rather than cuboctahedron edges).
The 4-coloring of Curtis bricks is useful in picturing the Klein correspondence.
Are there similar uses of cube 6-colorings? Or 4-colorings? (Group actions on
a 6-set are of considerable combinatorial and algebraic interest because of
the exceptional outer automorphism of S6.)
For a colored presentation of sextet space modeled with a rectangle,
as in the Curtis MOG, see . . .

Continuity

Actually, Dirac “bridged math and physics” much earlier —
“Spinors, which are a kind of square root of vectors, had been introduced
in algebra and also in physics as part of Paul Dirac’s theory of the electron.
A spin structure on a manifold allows such square roots to exist.”
