Thanks, Nathan. 10.5 seems to be dysfunctional, but I am communicating with Marc to figure out if it’s a screwup on my end, or if there’s something rotten in DMG :-} Justin > On Jul 19, 2025, at 05:32, Nathan Dunfield wrote: > > Justin, > > This is a known issue with the SageMath 10.6 binar

Hi, all, I just installed 10.6 from the 3-manifolds site. My system is Mac OS Catalina, 10.15.7, on an Intel MBP (2019). Attached is the crash report. Immediately after I installed the tarball, I ran “sage”, and the attached is the result. Help and pointers would be much appreciated. Thank

Hmm… what version of Sage are you using. I tried this with two MacOS versions, Sage 10.1 on Catalina (10.15.7) and Sage 10.3 on High Sierra (10.13.6). I had not problems on either version. Also, for less typing, this works as well: A = 6*O :-} Justin > On Jun 9, 2025, at 05:21 , 'MANUEL CORTE

Re: [sage-support] Number Field questions

2025-06-12 Thread 'Justin C. Walker' via sage-support
Hi, Chris, Thank you for that. I know about the .order method, but for reasons long past, I often use ZZ[a], and I was puzzled that Sage knows that the latter is an order in the number field (hence, one would think, contained in OK), but I could see no way to persuade the program to admit that

Hi, all, I am stuck in a twisty maze of passages within the number field code. Here’s an example: f=x^4+2 K.=NumberField(f) OK = K.maximal_order() a = OK.gen() O = ZZ[a] O.index_in(OK) !Boom: not matching ambients! It seems as if this should work, at least if I could figure out how to patch
