MATCH(exact) Read v40 backwards: rank 207 gets the first "a" and rank 0 the last "z" (207 = 7·26 + 25). Because 207 is odd, letter parity is now the opposite of rank parity. The cancelled letters (b, d, … z) fall on even ranks, which are RIGHT, and the survivors move to the LEFT, all 104. The sum is unchanged at 2848 (the same letters, reordered).
MATCHThe symmetry group of the 16×16 square restricted to these four operations is the Klein four-group: identity I, horizontal mirror H (col 1↔16), vertical flip V (row A↔P), and 180° rotation R. Each is its own inverse, and any two compose to the third. On the v40 atoms:
| op | atoms landing | off-disc ranks | cancel / survive (rank-order read) | value | parity kept |
|---|---|---|---|---|---|
| I | 208 | — | 104 / 104 | 2848 | 208 |
| H | 206 | 0, 207 | 103 / 103 | 2847 | 0 |
| V | 206 | 0, 194 | 104 / 102 | 2821 | 206 |
| R | 206 | 0, 193 | 103 / 103 | 2847 | 0 |

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
