Our complex is a natural generalization of the constructions by Panteleev and Kalachev and by Dinur et. al of a square complex (case t=2), which have been applied to the design of classical locally testable codes (LTC) and quantum low-density parity check codes (qLDPC) respectively.\n  We turn the geometric (cubical) complex into a chain complex by relying on constant-sized local codes $h_1,\\ldots,h_t$ as gadgets.
