Presentation of the absolute Galois group of Q₂

The 2-adic absolute Galois group

Model / AI: Claude Fable 5, GPT-5.5 Pro

Claude Fable 5 found the first candidate presentation for Roe, then a GPT-5.5 Pro harness run for Turturean produced an explicit presentation plus a long proof; passed Roe's 5,402-group verifier and two Lean developments, both conditional on unformalized classical inputs (nine and seven respectively). Not yet peer reviewed.
