Re: [sage-devel] Difficulty with Galois group

Also, I am not sure whether there is a practical algorithm to compute the Galois group when the extension is not normal (for splitting fields, there is one due to Susan Landau; however there are mod p techniques too)! On Apr 23, 2014, at 2:41 AM, Dima Pasechnik wrote: > On 2014-04-22, Jeroe

Hah, nice catch! I did not try either of them and that helps find out more: Apples-MacBook-Pro:~ apple$ sage --kash /Users/apple/sage/local/bin/kash: line 4: ./kash3: Bad CPU type in executable I get the above. I am using Sage Version 6.2.beta7, Release Date: 2014-04-08. So, how do I proceed w

Hello Sampath, I have tried to install kash and here are the results I get by passing in the commands you have passed sage: K. = NumberField(x^13 + 3*x + 5) sage: K.galois_group() --- TypeError

[sage-devel] Difficulty with Galois group

2014-04-19 Thread Kannappan Sampath
Hello sage-devel: I am trying to prepare a notebook for a SAGE demo at my institute. In rying to compute the Galois group, I am stuck here. SAGE complains that I have to install KASH while I already have KASH installed. sage: K. = NumberField(x^13 + 3*x + 5) sage: K.galois_group()
