Pegasus is the current software used in the Mind Sports Olympiad to generate questions, and is used by many mental calculators for training. It is maintained by George Lane and updated occasionally in a Dropbox folder, along with some related files. Contact George Lane (or me) for access.
I’m now hosting Pegasus on this website too – this will usually be up-to-date. The zipped folder download contains the Excel document and a separate text document explaining the categories and software.
