Dear Gap-Forum.

I noticed a strange behavior in the function 'CharTable'.

gap> g27:=AllThreeGroups(Size,27,IsAbelian,false);
[ Group( a1, a2, a3 ), Group( a1, a2, a3 ) ]
gap> G:=g27[1];; G.name:="G";;
gap> t1:=CharTable(G);;
Error, List Element: <list>[1] must have a value at
r := RootInt( Int( (D.deg - (D.num - anz) * D.degreePool[1][1] ^ 2) / anz ) )
... in
DegreeCandidates( D, d * mult ) called from
SplitTwoSpace( D, raum ) called from
CombinatoricSplit( D ) called from
DixonSplit( D ) called from
arg[1].operations.CharTable( arg[1] ) called from
..

GAP successfully computed the character table of all solvable
nonabelian groups of order at most 100, except those of order 27.
