% File : HWV052-1.001.002 : TPTP v8.2.0. Released v4.1.0.
% Domain : Hardware Verification
% Problem : Faulty channel 1 2
% Version : Especial.
% English : The problem of sending N bits over a faulty channel that can
% mutilate any one bit. We can use K extra bits to help us do this.
% Satisfiable means that it is possible, unsatisfiable means that
% it is not possible.
