% Domain   : Boolean Algebra (Ternary)
% Problem  : Ternary Boolean Algebra Single axiom is sound.
% Version  : [MP96] (equality) axioms.
% English  : We show that that an equation (which turns out to be a single
%            axiom for TBA) can be derived from the axioms of TBA.

%--------------------------------------------------------------------------
%----Include ternary Boolean algebra axioms
include('Axioms/BOO001-0.ax').
%--------------------------------------------------------------------------
%----Denial of single axiom:

    multiply(multiply(a,inverse(a),b),inverse(multiply(multiply(c,d,e),f,multiply(c,d,g))),multiply(d,multiply(g,f,e),c)) != b ).
