2013-08-20 13:47:54 +0100 | asked a question | Permutation Groups in Gaps Hi I have a group of size 1171875 given by generators and relations in GAP. To compute it's Schur Multiplier, I need a presentation of it as a permutation group. AsPermGroup takes forever (I have run it for over an hour) and I was wondering if there was a faster way. Thanks! (BTW I am not sure this is the right place to ask this question! I didn't see a GAP forum out there. If necessary, I can delete this post). |

2013-07-18 15:52:03 +0100 | asked a question | HAP installation Hi I installed gap_packages-4.6.4 onto my sage 5.6 installation. As a result HAP and HAPcryst directories showed up in my sage-5.6/local/gap/gap-4.5.7/pkg folder. However when I try to run LoadPackage("hap") or LoadAllPackages(), neither of these packages get loaded! A solution would be appreciated. Lalit |

2013-02-25 15:43:30 +0100 | answered a question | p-part of a class group Partial Solution: Elementary divisors and some factorization code gives me what I want. However, it would be nice to be able to coerce an abelian group into a group. |

2013-02-25 12:09:12 +0100 | asked a question | p-part of a class group Hi I am trying to compute the p-part of a class groups of some number fields. I was hoping to just call G.sylow_subgroup(p), but this function is not implemented for Abelian groups. In addition, invariants doesn't seem to work, for example, if G= C6, then G.invariants() returns [6], which doesn't seem correct. I would appreciate any advice on how to do this. For example, can I coerce an Abelian Group to just be a finite group? Note: I asked this on IRC without an answer. I hope it is not bad form to ask it here. Partial Solution: Elementary divisors and some factorization code gives me what I want. However, it would be nice to be able to coerce an abelian group into a group. |

2012-08-15 20:03:27 +0100 | asked a question | Error while installing Sage 5.2 Hi, I am trying to get Sage 5.2 running on my system (Ubuntu 11.10). I downloaded the lzma and ran ./sage and got the following: Traceback (most recent call last): File "/home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/bin/sage-ipython", line 18, in <module> import IPython File "/home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/lib/python2.7/site-packages/IPython/__init__.py", line 58, in <module> __import__(name,glob,loc,[]) File "/home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/lib/python2.7/site-packages/IPython/ipstruct.py", line 17, in <module> from IPython.genutils import list2dict2 File "/home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/lib/python2.7/site-packages/IPython/genutils.py", line 28, in <module> import subprocess File "/home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/lib/python/subprocess.py", line 429, in <module> import select ImportError: /lib/i386-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by /home/jain/Development/sage-5.2-linux-32bit-ubuntu_12.04_lts-i686-Linux/local/lib/python2.7/lib-dynload/select.so) I got the same error when running make. Any advice on how to get it working would be great. Lalit |
