The record

Purpose: Basix is a finite element definition and tabulation runtime library.
Basis evaluation: It evaluates finite element basis functions and their derivatives at a set of points.
Cell information: It provides geometric and topological information about reference cells.
Mapping: It supports push forward and pull back operations between reference and physical cells.
Degrees of freedom: It can permute and transform degrees of freedom to support higher order elements on arbitrary meshes.
Interpolation: It supports interpolation into and between finite element spaces.
Custom elements: Basix includes built in elements and allows users to define custom elements.
Element cells: The documentation describes creating finite elements on intervals, triangles, quadrilaterals, tetrahedra, hexahedra, prisms, and pyramids.
FEniCSx components: Basix is part of FEniCSx alongside UFL, FFCx, and DOLFINx.
Interfaces: Basix's core is written in C++, and most of its functionality is available through a Python interface.
License: The Basix repository identifies its license as MIT.
Installation: The repository gives `pip install fenics-basix` as an installation command.
Support: The project directs bug reports to its GitHub issue tracker and usage questions to the FEniCS discourse group.
Platform downloads: The FEniCS download page gives conda as the easiest way to start on macOS and other systems, and apt as the easiest installation route on Debian or Ubuntu Linux.
