Below is a list of proposed projects. Please edit and add your projects!
Combinatorics
Implementing Stanley chromatic symmetric function for posets
Mathieu, Eric, Alejandro, Chris, Nathann, Yan
Implementing boards for rook placements, Le diagrams (#14127)
- implementing Le diagrams
- include CombinatorialMaps if possible
- adding documentation and doctests
Alejandro, Kevin (testing/doctests), Bruce, Salvatore, Emily, Federico
Flow polytopes from permutation matrices and alternating sign matrices (#14654)
Jessica, Alejandro, Nathann, Emily, Laura
Implementation of k-tableaux and k-charge

Hypergraph visualization
Nathann
Combinatorial Species
Martin Rubey, Bruce, Mike, Florent, Tom D., Marguerite Thursday and Friday only
- code cleanup
- generation of unlabelled objects for composition and functorial composition via a group action framework
- multisort species (multivariate formal power series would be useful for that)
- add code by Andrew for Gamma-species
- support operations from symmetric function code for cycle index series
Conclude OEIS ticket #10358 (rebase after #13701, last doctests, and make urls clickable from the notebook
ThierryMonteil, Eric, Chris, Salvatore
