You (hongy) might be interested in Matrix Groups (Universitext) 2nd Edition by M. L. Curtis (Author) Which is a pretty good introduction; although the price is a little high. On 7/1/22 13:38, John H Palmieri wrote: Is this the sort of thing you're looking for? def matrix_rep(z):     """

It's strange that I see the output is temporarily correct and then gets replaced; you have to pay attention,  it's fast.  Like there is a censor/autocorrect kicking in after a write has taken plane. Can I put ..verb.. in a code cell?  I am trying to troubleshoot/track results. On 6/6/22

I think I have it; "view" expects  a "digraph"  not a "crystal" Try - #%%Latex B = crystals.Tableaux(['A',2], shape=[2,1]) G = B.digraph() view(G) print(B) print(G) --- Returns popup graph and inpage text - The crystal of tableaux of type ['A', 2] and shape(s) [[2, 1]] Digraph on 8

Well, that didn't work for me. But changing "view" to "show" produced a script that I can tell is targeted for something, not pdflatex.  Let me know if you know; maybe graphviz converter?  Loading doc2tex didn't help. Anyhow,  here is a "hack" that pops a popup that is correct.  A wrapper
