Dear Angel,

This is a known bug which is fixed in the latest version; please download version 1.15 from here and extract it in your /pkg directory of your gap installation:

   http://users.monash.edu/~heikod/cubefree.html

(This version should actually be listed on the gap website http://www.gap-system.org/Packages/cubefree.html but it isn't -- Alex?!?)

Anyway, the result of this computation is

gap> n:=NumberCFGroups(815409);
415

Best,
Heiko

Cubefree package but after 2 minutes processing my pc returns me this:

you can 'return;' after assigning a value

How can I fix this problem?
