Universality: Sayab-rule.

The Sayab-rule has the smallest glider-gun reported to date,

consisting of just four live cells at its minimal phases.

Sayab-rule is a binary 2D cellular automaton with a Moore neighborhood

and isotropic dynamics.

Sayab-rule, named after the Mayan-Yucatec word for a natural spring (of

running water).
