Ticket #12103 – Description
v9 v16 1 1 Sage has (or will soon have) fairly good implementations of dense matrices over `GF(2)`, over `GF(2^e)` (#9562) and over `GF(p)` (p prime, #4260). However, it uses generic code for dense matrices over `GF(p^n)`, p odd, n>1, `p^n<255`. 2 2 3 I suggest to use a major modification of `MeatAxe Release 2.2.4` instead of the basic implementation. More on the modifications and the reason for choosing an old release is explained in the comments. 3 The original suggestion was to use a major modification of `MeatAxe Release 2.2.4` instead of the basic implementation. The timings below are with that old version (it is identical with 2.2.3 except for the GPL licence, and 2.2.3 was before 1998). 4 5 I now suggest to try and do the same with the latest !MeatAxe release 2.4.24, which is from 2011. There also is an experimental 2.5.0 from 2003, but I think we shouldn't rely on that. 6 7 Here is the original ticket description: 4 8 5 9 This is awfully slow:
