Seen first in 8.3.beta0 ; see the relevant announcement in sage_release.

There is in fact no such GAP package in GAP 4.8. However, it is a part of optional Sage package database_gap

Important questions: is the package truly missing or is the check for the package broken? And is the package required in the first place to do that computation?

Replying to jdemeyer:

Thé package is *NOT* missing. And this happens even after a forced reinstallation sage -f database_gap.

I've never heard of such a package, see also https://www.gap-system.org/Packages/packages.html

a typo?

comment:5 Changed 21 months ago by dimpase

There is no such GAP package in GAP 4.8

There will be primgrp package (https://github.com/gap-packages/primgrp) in GAP 4.9.

OK, this needs the same treatment as Small Groups library in sage/features/gap.py. I'll provide a fix.
