the 16 binary boolean operators
Given: the set of binary operators contain all unary and nullary operators as a subset.
There are 2^(2×2)=16 possible binary boolean operators. In order, they are: FALSE, x AND y, x AND NOT y, x, y AND NOT x, y, x XOR y, x OR y, x NOR y, x EQV y, NOT y, x OR NOT y, NOT x, y OR NOT x, x NAND y, and TRUE.
