sagemath_homfly: Homfly polynomials of knots/links with libhomfly¶

This pip-installable distribution passagemath-homfly provides a Cython interface to the libhomfly library.

What is included¶

sage.libs.homfly

Examples¶

$ pipx run --pip-args="--prefer-binary" --spec "passagemath-homfly[test]" ipython
