Every row of 8 squares, and the 36 values they hold
Every row of 8 squares, and the 36 values they hold. A census of Kōnane rows: how many arrangements of a row of squares carry each value, with the shortest row carrying that value printed beside it. Most arrangements are worth nothing at all; the rest spread over numbers, halves and quarters, stars, switches and infinitesimals — the whole vocabulary of the theory, from a game that predates it.

1 essay calls konane-values. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about.

A game older than the theory

Kōnane was played on carved lava boards in Hawai‘i long before anybody wrote a brace notation, and its rule for losing is the normal-play convention arrived at some centuries early. Evaluate a row of it and the answers are halves, quarters, stars and infinitesimals — the theory's whole vocabulary, out of a game that was not built to display any of it.
