Dear Forum,

this is a bug in the function ExtensionsByGroupNoCentre of the grpconst
package. Thanks, Benjamin, for reporting this!

I will make the new version of grpconst including the bug fix available
in the next days. 

Note that the function ExtensionsByGroupNoCentre has been used in
the construction of some of the non-solvable groups in the SmallGroups
library. However, these groups are so small that the bug did not show
up in that calculation.

Best wishes,

Bettina
