I'm not sure what you did to try and group your maps. However, I believe
the command to use to create a single raster map out of several smaller
maps is r.patch. Please see the html documentation that comes with Grass
(starting point is documents/index.html). Select the raster commands
link and then the r.patch link. Please note that there are tips in the
"Notes" section that may be useful to you.

Hope this helps.
