• Combinatorial specification searcher

  https://github.com/PermutaTriangle/comb_spec_searcher

  The comb_spec_searcher package contains code for combinatorial exploration.

• Algorithms computing the preimages of sorting operators

  The file preim.sage contains algorithms developed by myself and Hjalti Magnusson for computing the preimage of any pattern class under two sorting operators: 1) A stack of depth d (you can put d equal to infinity); and 2) A queue. These are implemented in the computer algebra system Sage. What follow are instructions for using the algorithm. Please contact me via email if you find any bugs, want any clarifications or to suggest new features.
