# RadiRoot: Roots of a Polynomial as Radicals

RadiRoot is a package for the [GAP](https://www.gap-system.org) computer
algebra system. It can compute and display an expression by radicals for the
roots of a solvable, rational polynomial. Related to this it is possible to
create the Galois group and the splitting field of a rational polynomial.


## Requirements

The package is written for GAP version 4.7 or higher. It requires the packages
[Alnuth](https://gap-packages.github.io/alnuth/) in version 3.0 or higher and
[TransGrp](https://www.math.colostate.edu/~hulpke/transgrp/). In addition,
LaTeX and the dvi viewer xdvi are recommended for displaying the results.


## Installation

The installation follows standard GAP rules. So the normal way to install is
to unpack the archive in the `pkg` directory, which will create a
subdirectory `radiroot`.


## Using RadiRoot

Please consult the RadiRoot manual for information on how to use it. It is
accessible via the builtin help system of GAP. The package homepage, which
also links to the manual, is at
  <https://gap-packages.github.io/radiroot/>
