Oct 4, 2023 at 17:13 comment added Mare @MartinBrandenburg It is a quotient of the path algebra with one vertex and 3 loops a,b,c.
Oct 4, 2023 at 12:07 comment added Dave Benson Try it as a path algebra with just one vertex. It should work...
Oct 4, 2023 at 11:45 comment added Martin Brandenburg @Mare Can I enter the algebra with QPA in GAP? Looking at the documentation, it only works with path algebras?
Oct 4, 2023 at 5:03 comment added Mare @MartinBrandenburg There is a magma online calculator that can do some simple computations: magma.maths.usyd.edu.au/calc Also the GAP package QPA is good to enter those finite dimensional algebras as in this answer.
Sep 30, 2023 at 23:07 comment added Martin Brandenburg Yes. I came from Gap actually ^^
Sep 30, 2023 at 22:37 comment added Dave Benson Well, Gap is free and does quite a lot of what Magma does. It's worth trying.
Sep 30, 2023 at 16:40 comment added Martin Brandenburg Thanks a lot! Unfortunately, I don't have access to Magma. I checked the website, apparently I cannot just download or pay for it. I tried to work on these questions with SageMath, but apparently it doesn't really work or I am missing something (for example, in SageMath, $\mathbb{Q}[x]/\langle 1 \rangle$ is not the zero ring, and I don't know why).
Sep 30, 2023 at 15:23 comment added Dave Benson And then, if you change it to $a^3=0$, $b^4=0$, $c^4=0$, magma doesn't finish in a reasonable time when $p=5$, which suggests it might be infinite dimensional.

Sep 30, 2023 at 14:53 comment added Dave Benson If you let $u=v=1$ and $w=-1$, then using the same code, you get these same dimensions $20n-24$, seemingly independent of $p$. Mathjax insists on interpreting the star symbol, so I can't copy and paste the code here, but it's simple enough to do yourself.
