And as correctly noticed, the #17251 is not in Singular 4.0.1 Martin Lee, the former coauthor of 'Singular/factory' is meanwhile very familiar with 'factory' and underlying algorithms and is able to fix bugs quickly. He fixed all bugs I discovered until now! The last fix is from today:https://github.com/Singular/Sources/commit/d1b07bbb98d7132b6aa0cda7d48dc948e89dae43 So if anybody is able to (auto) detect remaining bugs in Singular's recent 'factory' (e.g. in 'char_series()' or 'factorize()' ), in any kind of supported rings, please do so timely. I have no idea for how long Martin Lee will still maintain 'factory'. Jakob Am Samstag, 1.
