"In my experience, every kind of writing requires
some kind of self-soothing Jedi mind trick, and,
when it comes to essay composition,
this rectangle is mine."
— Zadie Smith in The New Yorker, Sept. 22, 2025.
A mind trick that is perhaps less self-soothing —
The dimensional reduction above, from six affine dimensions over
GF(2) to four dimensions, is, like a similar reduction in the previous post,
done by considering only even-sized subsets, then considering as elements
only the boundaries between these subsets and their complements . . .
and the Galois (XOR) sums of those boundaties.
