[GAP Forum] how to use the hilbert function after loadpackage singular

[Alexander Konovalov]

Hi Martin,

It's always useful to include the error messages in such reports.
What is the error message that is displayed? What is 'stdhilb' -
there is no such function in GAP and packages redistributed with it.
