A boolean function is a function of the form f: Bn -> B, where B = {0, 1} and n is a non-negative integer called the arity of the function. Some Boolean functions are projections: pnk(x1, ..., xn) = xk. And given an m-ary function f, and n-ary functions g1, ..., gm, we can construct another n-ary function: h(x1, ..., xn) = f(g1(x1, ..., xn), ..., gm(x1, ..., xn)), called their composition. A set o
