substituting using a matrix (not Options, not a ring map) can still give the wrong/unexpected answer. Here are two situations (one over QQ, the other over CC_53).
It should be easy to fix this, Dan,…

Hi! I'm trying to use `GaloisFields` as an element type in matrices, but I'm running into MethodErrors when using some of the stdlib matrix functions, some examples:
```julia
using GaloisFields

Hey Justin, just had a chat with @kburns on spin-weighted spherical harmonics, which
1) remove the cos scaling when calculating gradients (convenience and simplicity)
2) simplify meridional gradi…

Hi,
I am trying to symbolically compute the determinant of a 50x50 matrix using the Berkowitz method on a multi-core machine. It parallelizes on one of the machines I tried but does not use all the…

Our Marlin code base deserves some cleaning up. We still have left-overs from Marlin's initial AHP which are not necessary due to the coboundary sumcheck, and there are some structural improvements by…

We propose a new C++ library to compute Groebner basis over finite fields with the F4 algorithm.
This library works on prime fields of characteristic < 232
