[GAP Forum] Bug in filter for testing solvability?

[John Dixon]

Using GAP 4.4.5 (May 2005) I obtain the following

gap> l529 := AllPrimitiveGroups(DegreeOperation, 23^2, IsSolvable, true);
[  ]

I seem to get the correct answer when I use

gap>  AllPrimitiveGroups(DegreeOperation, 23^2);;
gap>  Filtered(last, IsSolvable);


P.S.  I am frequently reminded how grateful I am to all the people who 
have worked to make GAP such a useful tool.
