[GAP Forum] Lattice

Dear Kurt,

Yes, there is LatticeSubgroups to calculate it:

http://www.gap-system.org/Manuals/doc/ref/chap39.html#X7B104E2C86166188

and you may use DotFileLatticeSubgroups to save the image to a file, or
use the XGAP package (http://www.gap-system.org/Packages/xgap.html, does
not work under Windows) to explore the lattice interactively (see e.g. the
picture at http://www.gap-system.org/ukrgap/Examples/XGAP2.png

Hope this helps,
Alexander
