MGroups is a mathematica package that implements a part of finite group theory. It offers a user-friendly interface for performing a range of computations involving finite groups including Z_n, U_n, D_n, S_n, and more. The package allows users to define and analyse groups through Cayley tables and provides functionality for investigating group operations, subgroup structures (lattices), group morphisms, and more. Each group is defined in terms of its Cayley table representation itself, and operations are applied appropriately.

Computational tools play a vital role in modern mathematics by automating complex and often tedious calculations, thereby freeing users from manual labour and enabling deeper exploration of abstract concepts. In that essence, MGroups is designed primarily for undergraduate students beginning with group theory, as well as for educators seeking a user-friendly tool to demonstrate group-theoretic concepts interactively.
