Ignore  I accidentally pushed to the wrong branch. I pushforced the right one back now.
comment:20 Changed 11 months ago by
Thank you Darij and Travis for your hard work!
Some other bases that would be nice to code, if you guys have time  these are the sums of M's over some order on ordered set partitions, so maybe the only work is to code the orders:
 Q basis of BergeronZabrocki (https://arxiv.org/abs/math/0509265 start of section 6);
 The fundamental and multiplicative bases from NovelliThibon (https://arxiv.org/abs/math/0605061 lines 5556; section 2.6 and line 47).
 Their dual bases in the dual of WQSym.
Let me know if I can help. (But I'm in an antipodal timezone from you.)
comment:21 Changed 11 months ago by
Please open up followup tickets for each of these bases and feel free to work on them today. I/We can work on them tomorrow for us.

Darij, you will probably want more documentation (including references). Feel free to add. Otherwise this should be ready.
New commits:
Moving shuffle products with overlap to combinat/shuffle.py.
Extending shuffle products with overlap to more general iterables.
Added set of all ordered set partitions.
Initial version of WQSym and new folder for CHAs.
