Re: [sage-devel] Errors in determinant of 'large' symbolic matrices as opposed to working over better rings

Currently making sage_9.3 on machine so I can have open a new ticket and have a deeper look, but I'm quite convinced it is somehow a problem due to the complexity of the calculation in the symbolic ring. Firstly note that the answer det(L)=0 is the correct one (you can either trust this from t

[sage-devel] Apple M1 chip

Hello, There is a thread [1] on sage-support about using Sage on the new Apple M1 ARM 64-bit based laptops. I have one of these, so I decided to investigate, since this M1 processor is very, very impressive regarding the compute / watt ratio. Tom Judson asked: > I have a new MacBook Air with an

Re: [sage-devel] Errors in determinant of 'large' symbolic matrices as opposed to working over better rings

I created trac ticket #31077 to continue this discussion. But first I simplified the example a bit more by making some substitutions to reduce the number of variables, and changing the names to a,b,c,d,e,z. Also, I eliminated the need to compare with the
