RadiRoot: Roots of a Polynomial as Radicals

RadiRoot is a package for the GAP 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 in version 3.0 or higher and 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/
