# The DSP Package
This project was forked from [difsets](https://github.com/dylanpeifer/difsets). 

The original algorithm functions by finding difference sums, which are potential images of **difference sets** in quotient groups of the original group, and searching their preimages. In this way, the search space can be dramatically decreased, and searches of groups of relatively large order (such as order 64 or order 96) can be completed.

In this project, I made the following contributions:

1. Expand the original algorithm with the **multiplier theorem**.
2. The original algorithm only searchs **difference sets**, I made it applicable for **difference set pairs, divisible difference sets, divisible difference set pairs**.

# Installation

To install, first download this repository in the `pkg`directory of one of your GAP root directories. After installation, the package can be loaded at the GAP command prompt by typing

    gap> LoadPackage("dsp");

after which the dsp banner should appear on the screen.
