Dear all,
We'd like to add a new optional package Eigen (https://eigen.tuxfamily.org).
It will improve performance of at least one of the optional packages (semigroup)
of (lib)GAP, and hopefully to develop a new Python interface to it to
improve linear algebra (Eigen is actually well-supported by pybind11).
It's a very popular package, supported by all major Linux distros etc.
Any objections?
Best,
Dima
