I applaud the Axiom community's efforts to build a Computer Algebra Test Suite to objectively rate the performance of the various systems on a wide range of problems. To help in that cause, available now at http://www.apmaths.uwo.ca/~arich/ are translations of the 43,000+ integration problems in the Rubi test-suite expressed in Axiom/FriCAS and Maxima syntax, as well as the previously existing translations in Maple and Mathematica syntax. Developers are free to include all or some of these problems in CATS or other CAS test-suites being built.
Please let me know if you encounter errors in the translations, especially in the definitions of special and hypergeometric functions, so I can remedy them.
