KNOT STRUCTURES — CORPUS DOWNLOAD  (2026-10-31)

WHAT THIS IS
  490 machine-generated knots, each given as
    <name>.fseries                      — the Fourier centerline of the knot's space curve
    <name>_complete_invariants.json     — curated invariants + PD code(s) + consistency checks
  A growing catalogue of (mostly hyperbolic) knots. The sculpture curves (20 curves; XYZ
  comes in two executions) are NOT in this archive: sculptures and their curves are (c) all rights reserved.

HOW TO VERIFY
  The invariants come from established software (SnapPy, SageMath, Regina, knotpy).
  Each *_complete_invariants.json carries the PD code(s); recompute any invariant
  yourself with those tools. We drive the tools; we do not replace them.

WHAT IS NOT INCLUDED
  The sculpture curves (see above) and the code. The identification pipeline is open source
