double-6
An earlier, coarser reading mistook it for a modest twelve-crossing knot; resolved faithfully it proves genuinely intricate — determinant 21987², amphichiral, with a crossing number between 50 (from the span of its Jones polynomial) and 78 (its diagram). That places it well beyond the standard knot tables, where the HOMFLY polynomial can no longer be computed — its identity here rests on invariants the pipeline reads directly from the geometry.

See its Seifert surface in 3D →An orientable surface whose boundary is this knot. Built from the braid word: one disc per strand, one half-twisted band per letter. That its boundary is this very knot — and not its mirror, and not the unknot — was checked against the record: determinant, signature and Alexander polynomial.
