Life after exchange

B345678/S35678

Birth rule

Survival rule

Birth: 3, 4, 5, 6, 7, 8. Survival: 3, 5, 6, 7, 8. These counts read the fully exchanged intermediate board.

Pair exchange

Neighbor counts 578

Trigger mode

Periodic interval8

Periodic mode commands every pair on Steps 8, 16, 24, and so on. The value remains editable and preserved in neighbor mode.

Neighbor exchange counts

In neighbor mode, either endpoint seeing 5, 7, 8 neighbors commands one exchange for the pair. Both matching still means one exchange. These counts read the original frozen board.

Switchboard

Permanent distant pairs exchange their present dead/alive states on a configurable beat or local-neighbor trigger, then ordinary Life reacts to the fully mixed field.

Current composition

01A seeded random perfect matching gives every position exactly one distant counterpart; no cell pairs with itself.
02Each endpoint compares its frozen Moore count with 578; either match commands the pair.
03A commanded pair exchanges its two dead/alive states exactly once. Equal states still record a command; simultaneous endpoint triggers never cancel.
04B345678/S35678 reads the complete exchanged board, then commits every final state synchronously.
05The coupling never changes neighbor membership, evolves, or makes a random call after Reset.

Color view shows established life in lime, Life births in cream, and living states that arrived through an effective exchange and survived Life in gold. Dead states remain background. Inspect pair draws a violet line to the selected cell's only counterpart and outlines local neighbors. Written evidence gives both frozen trigger counts, the pair command source, the exchange stage, the Life count on the fully exchanged board, and the final result. Arrow keys move the cursor; Enter paints when inspection is off; P plays or pauses; S advances one complete exchange-then-Life Step.

Either endpoint seeing 578 neighbors exchanges the pair before Life. Watch local crowding send state through distant links.
