I tried to access the database of Bieberbach groups (more precisely https://lbfm-rwth.github.io/carat/doc/bieberbach.html) with the hope of constructing in GAP the Bieberbach groups of dimension 5 with trivial center (of which there are 101, see https://emis.de/ft/51901). However, the website seems broken, and even trying to obtain the counts leads to the main page https://www.art.rwth-aachen.de/go/id/reil/ (via http://wwwb.math.rwth-aachen.de/cgi-bin/sdb.html) rather than to the answer.
