Is this file added by some optional package, such as meataxe? Without meataxe, the directory src/sage/rings/function_field has a file function_field_ideal.py but no file ideal.py --- and sage: Oinf = F.maximal_order_infinite() gives a NotImplementedError. > I created https://trac.sagemath.org/ticket/26389 > (Simon, I have cc-ed you). Note that the ticket summary has "Hisenbug" for "Heisenbug" and it might make sense to start the ticket description with an indication that this happens with Meataxe installed. -- You received this message because you are subscribed to the Google Groups "sage-release" group.

Do you know offhand (i.e., don't spend much time on this) of a simple way I can extract out the relevant matrix computation? This is not a minimal example, and it would be useful to get it down smaller. I created https://trac.sagemath.org/ticket/26389 (Simon, I have cc-ed you).
