It is not as friendly and easy to use as some of the competition, but I don't think that was their goal. With this program, you can download drivers for your computer and large (over 8 GB) driver packs to update drivers on almost any computer. Snappy Logo Gear; Countersinks & Counterbores.

Snappy

  • Version 3.0 (April 2021): New features include:

    • Incorporates Zoltán Szabó’s program forcomputing Knot Floer homology, see knot_floer_homology. This can compute theSeifert genus of a 25 crossing knot in mere seconds!

    • Topological slice obstructions of Herald-Kirk-Livingston, seeslice_obstruction_HKL.

    • Faster “local” algorithm for jones_polynomial.

    • Cohomology fractals added toinside_view.

    • Convention changes: Sign of knot signature (now positive knots havenegative signatures), choice of braid generators (now positivegenerators give positive crossings).

    • Updates to methods cusp_translations, cusp_areas, short_slopes. Also Linknow accepts DT codes.

    • Support for SageMath 9.3, Python 3.9, and macOS Big Sur.

    • macOS app now code-signed and notarized.

    • SnapPy now requires Python 3.6 or newer.

  • Version 2.8 (June 2020): New features include:

    • Raytraced interior views of a hyperbolic 3-manifold via theinside_view method, see alsoimages anddemo video.

    • Verified computations: Several new features:

      • Complex volume (and thus the Chern-Simons invariant) for bothcusped and closed manifolds, seecomplex_volume.

      • Disjoint cusp neighborhoods by the method cusp_areas which usescusp_area_matrix.

      • Cusp shapes (see cusp_info).

      • Finding all short_slopesin disjoint embedded cusp neighborhoods.

    • The census HTLinkExteriors hasbeen extended to 15 crossing knots (contributed by MalikObeidin).

    • The census CensusKnots has beenextended to triangulations with 9 ideal tetrahedra.

    • Support for SageMath 9.0 and macOS Catalina.

    • Development moved to GitHub.

  • Complete version history.
