"When we say a thing is unreal, we mean it is too real,
a phenomenon so unaccountable and yet so bound to
the power of objective fact that we can’t tilt it to the slant
of our perceptions." — DeLillo, 2001

A Tale of Two Omegas

The Greek capital letter Omega, Ω, is customarily
used to denote a set that is acted upon by a group.
If the group is the affine group of 322,560
transformations of the four-dimensional
affine space over the two-element Galois field,
the appropriate Ω is the 4×4 grid above.
See the Cullinane diamond theorem .
If the group is the large Mathieu group of
244,823,040 permutations of 24 things,
the appropriate Ω is the 4×6 grid below.

Another View of Point Omega
Not by Don DeLillo —
Those apt to be seduced by language, either secular or religious,
might note that the author of the Point Omega book above is also
the author of Abuse of Language, Abuse of Power —
Hemingway fans might note as well a website whose background

Point Omega …
In this post, "Omega" denotes a generic 4-element set.
For instance … Cullinane's
or Schmeikal's
.
The mathematics appropriate for describing
group actions on such a set is not Schmeikal's
Clifford algebra, but rather Galois's finite fields.

Point Omega*
Fareed Zakaria in an online Aug. 21
New York Times book review —
" Most intellectuals think ideas matter.
In one of his most famous and oft-quoted lines,
John Maynard Keynes declared, 'Practical men
who believe themselves to be quite exempt from
any intellectual influence are usually the slaves
of some defunct economist. Madmen in authority,
who hear voices in the air, are distilling their frenzy
from some academic scribbler of a few years back.'
Scott L. Montgomery and Daniel Chirot concur,
arguing that ideas 'do not merely matter; they matter
immensely, as they have been the source for decisions
and actions that have structured the modern world.'
In The Shape of the New: Four Big Ideas and How
They Made the Modern World , Montgomery and
Chirot make the case for the importance of four
powerful ideas, rooted in the European Enlightenment,
that have created the world as we know it.
'Invading armies can be resisted,' they quote
Victor Hugo. 'Invading ideas cannot be.' "
