tetrahedron_jaskowiec_rule, a Python code which returns quadrature rules, with exactness up to total degree 20, over the interior of a tetrahedron in 3D, by Jan Jaskowiec, Natarajan Sukumar.
The quadrature rules are described in terms of barycentric coordinates (a,b,c,d), with weights w that sum to 1.
