%    Short Single Axioms for Boolean Algebra

%    Journal of Automated Reasoning 29(1):1-16, 2002.
%
% is a single axiom for Boolean algebra in terms of the Sheffer Stroke.
%
% We believe that this result was already shown using Waldmeister, but
% we have not seen that proof and don't know the details of how that
% proof was found.
%
% See http://www.cs.unm.edu/~veroff/BA/ for a discussion of the original
% problem, and note that Candidate C2 is Equation 4 from the original
% candidates list.
%
% This proof makes use of the defined functions C() and D(),
%
%    C(x) = f(x, f(x, x))
%    D(x) = f(f(x, x), x)
%
% and derives the known system
%
%    f(x, y) = f(y, x)             # label("Commutativity").
%    f(f(x, y), f(x, f(y, z))) = x # label("Equation 26a").
