Exact expansion

((exists dp_index_gap. dp_index_gap + S i = l) /\ ((((~((S i) = 0) /\ (exists dp_gap. dp_gap + S (S i) = m))) /\ (((~((y) = 0) /\ (exists dp_gap. dp_gap + S (y) = m))) /\ (exists dp_u dp_v. (S i) * (y) + m * dp_u = (t) + m * dp_v)))))

This node is notation, not a theorem, axiom, predicate constant, or kernel rule. The elaboration layer must expand it before proof checking.
