x_{1} (object, event, string, etc.; anything toggleable with x_{2}-many states) represents a bit/shannon/trit/nat (information unit) of logarithmic base x_{2} (default: 2) where states x_{3} (ordered list) respectively represent bit states x_{4} (ordered list; same length as x_{3})

Examples for binary bits (x1 when x2 = 2): a 0-xor-1 string of length one, a coin flip, the toggleable states of an electrical switch, the direction that a car drives down a road, etc.
