Description: This package provides methods for constructing and testing matrix presentations of the representations of SL(2,Z) whose kernels are congruence subgroups of SL(2,Z).

Irreducible representations of prime-power level are constructed individually by using the Weil representations of quadratic modules, and from these a list of all representations of a given degree or level can be produced.  The format is designed for the study of modular tensor categories in particular, providing symmetric matrix presentations of each representation.
