# GAP package Prescribed Automorphism Groups (PAG)

* Website: https://vkrcadinac.github.io/PAG/
* Repository: https://github.com/vkrcadinac/PAG

PAG is a [GAP](https://www.gap-system.org) package for constructing 
combinatorial objects with prescribed automorphism groups.

The package uses external binaries. To compile them on UNIX-like
environments, change to the 'pkg/PAG-*' directory of your GAP 
installation and call

        ./configure.sh 

This produces a Makefile in the current directory. Now call

        make all

to compile the binares. They are placed in the 'bin' subdirectory.
To load the package start GAP and type

        LoadPackage("PAG");

For details on how to use the package see the documentation in the
'doc' subdirectory.
