Research activity
Discovery, exposition and formalization
Mazur and GPT-5.6 Pro supplied the original result; Tao digested its mathematics and directed the second formalization, whose project credits Claude Opus 5.
Two formalizations of a descended argument do not automatically constitute two independent mathematical proofs.

Recorded authorship
Terence Tao
Terence Tao performed mathematical digestion and simplification with substantial AI assistance; this descends from Mazur’s argument and is not an independent discovery route.
