- You will obtain here a tar file of all the files necessary to run Sage implementation of the above algorithm together with various functions to deal with spherical varieties that are group imbeddings. This is written by Shaun van Ault based on the above GAP package. (Caution: one needs to use sage-4.6 for the package to work properly.)

- Here you will find examples of functions in the above package that can be used to deal with spherical varieties that are group imbeddings. This written by Shaun van Ault.
