2011-08-15 17:32:38 +0100 | commented answer | bug in minimal polynomials of finite fields Thanks! (Are you a Sage developer? Should I consider the bug reported?) |
2011-08-15 15:30:28 +0100 | asked a question | bug in minimal polynomials of finite fields In a compiled version of 4.7 (64 bit, Debian Sid), I get: ----------------------------------------------------------------------
| Sage Version 4.7, Release Date: 2011-05-23 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: F.<a>=GF(2^64)
sage: a.minpoly()
_3 = x^64 + x^33 + x^30 + x^26 + x^25 + x^24 + x^23 + x^22 + x^21 + x^20 + x^18 + x^13 + x^12 + x^11 + x^10 + x^7 + x^5 + x^4 + x^2 + x + 1

sage: b.minpoly()
_5 = x^128 + x^7 + x^2 + x + 1

_6 = x^128 + x^7 + x^2 + x + 1
Is this a bug or am I doing something stupid? Thanks, Luis |

2011-05-27 11:48:59 +0100 | asked a question | Fedora 14 binary Dear all, I just installed sage-4.7-linux-64bit-fedora_release_14_laughlin_-x86_64-Linux.tar.lzma on my computer running Fedora 14: boole[~]$ uname -a

Can this be fixed or should I just compile it from source. Thanks, Luis |
2011-03-29 16:46:10 +0100 | commented answer | no linewidth with parametric plot Thanks. That works (of course). It is too bad that the syntax is not uniform... |

2011-03-28 18:41:32 +0100 | asked a question | no linewidth with parametric plot It seems that there is no option for linewidth in parametric_plot. (2D in my case.) Is that true? Any way to make the graph thicker? |

sage: An error occurred while installing pari-2.4.3.svn-12577.p9
Please email sage-devel http://groups.google.com/group/sage-devel
explaining the problem and send the relevant part of
of /scratch/local/sage-4.6/install.log. Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/scratch/local/sage-4.6/spkg/build/pari-2.4.3.svn-12577.p9 and type 'make check' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
(cd '/scratch/local/sage-4.6/spkg/build/pari-2.4.3.svn-12577.p9' && '/scratch/local/sage-4.6/sage' -sh)
When you are done debugging, you can type "exit" to leave the
subshell.

Any ideas? Thanks, Luis |
