DD is isomorphic to the HP counter example input. DD simulated by HHH cannot possibly halt. The DD input to HHH cannot possibly halt and deciders are not allowed to report on non-inputs. > The question you continually fail to address is what HHH() does with > arbitrary input programs. > -- Copyright 2025 Olcott "Talent hits a target no one else can hit; Genius hits a target no one else can see."
