ITAP requires GAP interface to singular [CG12] which is another GAP package. Nowadays, it comes bundled with GAP 4.7+. If your gap installation doesn't have this package you can follow the instructions in [CG12] to install it. To get the newest version of ITAP, download the .zip archive from https://github.com/jayant91089/itap and unpack it using
\[\texttt{unzip itap-x.zip}\]
Do this preferably inside the \(pkg\) subdirectory of your GAP 4 installation. It creates a subdirectory called \(itap\). This completes the installation of the package. If you do not know the whereabouts of the \(pkg\) subdirectory, invoke the following in GAP:
GAPInfo.("RootPaths");
Look for pkg directory inside any of the paths returned. One can then start using ITAP by invoking
\[gap>\]
LoadPackage( "itap");
from within GAP. This would automatically load the GAP interface to singular, so you don't have to load it seperately.
