Short Description

The Polenta package provides methods to compute polycyclic presentations of matrix groups (finite or infinite). As a by-product, this package gives some functionality to compute certain module series for modules of solvable groups. For example, if G is a rational polycyclic matrix group, then we can compute the radical series of the natural Q[G]-module Q^d.
