The Symmetry
Loom

Twelve beads. A little thread.
How many ways can a thing remain itself?

01 / the working thread

Make a pattern. Try to fool it.

02 / what survives

A pattern’s little family of symmetries

Symmetry order
8

Exact matches among all 24 moves.

Minimal repeat period
3

Smallest clockwise repeat, in beads; 12 means no shorter repeat.

Rotational orbit size
3

Distinct arrangements under rotations only. Here it equals the period.

The stabilizer is the set of moves that leave this thread unchanged. ✓ survives; · changes it. Tap any move to compare it above.

↑ See the comparison on the working thread

Two surviving moves make another. Try composing them.

Do the first move, then the second. If both belong to the stabilizer, their composition must belong too. The order of moves can matter.

How the labels work

Calculations use positions i = 0…11, shown on the loom as beads 1…12. Rk sends i to i + k (mod 12). Fk sends i to k − i (mod 12). R0 is the identity: do nothing. F0 fixes beads 1 and 7; F1 swaps beads 1 and 2 and has an axis between them. There are twelve distinct rotations and twelve distinct reflections. Bead numbers are measuring guides, not part of the binary pattern.

03 / four discoveries to take home

Follow the loose end

0 of 4 discoveries filed

Work in any order. A filed discovery records that you found an example; the working thread can keep changing.

A tug in the right direction

Try the first discovery, or choose another.

04 / the specimen drawer

Same beads, different possibilities.

Pin a thread, then change the loom. Every pinned specimen is compared with your current thread. Reload one to keep investigating. Session only; up to twelve distinct pins.

Pin a specimen to begin a comparison.

About this loom · mathematics, metaphor & sources

Keep the thread and the theory separate.

Established mathematics. This app computes the dihedral symmetries of a twelve-position binary circular pattern. It tests all 24 actions exactly. The group identities, stabilizers, periods and orbits here concern these bead patterns only.

AI-authored analogy. The cabinet, specimens and four discovery challenges are original playful mechanics. This is not a model of consciousness and not a measurement of valence. More symmetry is not a score for pleasure, beauty or personal progress. The stages are not jhanas or a treatment.

The source proposal. Michael Edward Johnson’s Symmetry Theory of Valence proposes that, given a mathematical representation isomorphic to an experience, symmetry of that representation encodes pleasantness. A suitable formalism for consciousness is still needed; neuroimaging proxies depend on chains of inference. It does not follow that a more symmetric picture makes someone feel better.
