GL(2,4) isnt supported because it needs $\mathbb{F}_4$ which also needs a better implementation for Galois field.
But a better implementation of Field needs a better implementation of Ring, particula…

Currently, factorization is broken over fraction fields over non-prime finite fields:
```
sage: k. = GF(9)
sage: K = k['t'].fraction_field()
sage: R. = K[]
sage: f = x^3 + a
sage: f.factor()
x^3 + …

I have several packages (CyclotomicNumbers, Combinat, Gapjm) where heavy use of factor is made -- mostly for other number-theoretic functions, like totient, divisors, prime_residues, primitive roots. …

1) The following should be an `ArithmeticError` since whether or not the polynomial factors depends on the `O(3^20)` error term (`t^2 - 3^20` factors while `t^2 - 3^21` does not):
```
sage: R. = Po…

There are currently no known counter examples where Singular would return an incorrect factorisation. It might be very very slow but does not return wrong answers as far as we know. Hence, we should…

The desire to easily look at sequence entries in terms of their prime factorizations is one of the primary motivations/justifications for having a Numberscope backend distinct from the OEIS. This info…

Today we (NH, LH, CT, JV) discussed how to handle expansion & contraction propagation through slices, in the labelled world. There are four scenarios (see https://arxiv.org/abs/1902.03831 section 5.1)…
