Dear Forum, I get the same strange behavour on 4.4.10, too: GAP4, Version: 4.4.10 of 02-Oct-2007, i686-pc-linux-gnu-gcc gap> Intersection([1..3],[1..3]); [ 1 .. 3 ] gap> Intersection([-3..-1],[-3..-1]); [ -3 .. -1 ] gap> Intersection([-1..1],[-1..1]); [ ]
And that's what I am running on. $ uname -a Linux *** 2.6.25.10-custom #3 SMP Mon Jul 14 22:54:07 BST 2008 i686 GNU/Linux So that's a hardware-dependent behavour, apparently.
