I presume you are using my `Abstract Algebra with GAP' notes. When these were written I had expected that version 4.5 would have been released over a year ago. Alas it was not and therefore some of the functionality described is not yet available in the released version. > > I've been having trouble finding how to get this function to work, I have > only been able to find one think online regarding it which was a file which > you read in GAP called "latticdot.g" but reading this still gives the I presume you mean the file available at: http://www.math.colostate.edu/~hulpke/latticedot.g I checked and indeed spotted that a line DeclareGlobalFunction("DotFileLatticeSubgroups"); is missing at the start. I have updated the file and with this correction (or issuing this line before reading in) it should work now. Apologies for the problem!
