 # Description
 
-CrystKit is a GAP package designed to manipulate and analyze crystallographic groups. It offers a variety of functionalities, including space group simplification on any basis, minimal generating set computation for solvable space groups, isomorphism detection between space groups, enantiomorphic pair existence checking, efficient orbit computation of the system of the space group's nonprimitive translation vector (SNoT), see the definition 37 on page 23 [here](https://www.math.ru.nl/~souvi/krist_09/cryst.pdf) for more tails and rapid identification of space groups (up to six-dimension) based on [CARAT](https://github.com/lbfm-rwth/carat). It also encompasses the calculation of allowed orders of point groups in any dimensional space groups, aka, the crystallographic restriction theorem in a given dimension, and conjugacy determination between two finite matrix groups based on [RepnDecomp](https://github.com/gap-packages/RepnDecomp).
