All possible 2-input logic gates, 16 gates in all. I wanted a reference for building complex logic circuits.
Truth Table:
A B 0 & α A β B ^ | `| `^ `B γ `A δ `& 1
0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1
0 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1
1 0 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1
1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1
^ is XOR (as in C)
` is NOT (for space reasons)
α A&`B
β `A&B
γ A|`B or `β
δ `A|B or `α
