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 61 (111101 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|1|1|1|0|1|
-----------------------------------------------
