 OFFSET 0 COMMENTS An Elementary Triangular Automaton (ETA) is a cellular automaton in the triangular grid where cells hold binary states and rules are local to the first neighborhood. There are 256 possible ETA rules. Rule 37 (100101 in binary): ----------------------------------------------- |state of the cell |1|1|1|1|0|0|0|0| |sum of the neighbors' states |3|2|1|0|3|2|1|0| |cell's next state |0|0|1|0|0|1|0|1| ----------------------------------------------- REFERENCES Paul Cousin, "Triangular Automata: The 256 Elementary Cellular Automata of the 2D Plane", Complex Systems, 33(2), 2024.
