unable to retrieve factors of 2(220)-1

So, it looks fine at the server side and must be an issue with `factordb-python`.

unable to retrieve factors of 2(220)-1

Any update?

Computing roots "modulo an integer" is not supported

I've fixed this issue in my recent pull request.

QEPCAD prints `finish &`

This issue is fixed in 10.3, which can be seen from running the code at Sagecell: https://sagecell.sagemath.org/?q=qiypmw

square multivariate polynomials are incorrectly detected for some term orders

> The failed conversion raises an unexpected `ValueError`, and `is_square` erroneously takes this to mean that there is no square root. Isn't that behavior of `is_square` unsafe? Putting aside a...

Set bug in comparison of finite groups

I'm not sure if `Set` should be blamed here. Elements of `pointstabilizers[0]` and `subgroup_check[0]` have different parents: ``` print( pointstabilizers[0][0].parent() ) print( subgroup_check[0][0].parent() ) ``` tell us > Permutation Group...

QEPCAD Timeout

I this issue is irrelevant to Sage, it should be reported to Qepcad developers.

QEPCAD Timeout

@anirjoshi: No, it's not a right place as Sage is not responsible for issues in other packages, which it uses as blackboxes. For Qepcad issues, please check its homepage: https://www.usna.edu/CS/qepcadweb/B/QEPCAD.html

Use Singular `chinrem` function for `CRT_list(…, algorithm="singular/pari")`

There is also implementation of `ChineseRem` in GAP: https://docs.gap-system.org/doc/ref/chap14.html Shouldn't it be included as well for completeness?
