yes, the leading "i" and "c" restrict the abbreviation to insert mode
and command-line mode, respectively. The "nore" part prevents the just
expanded right-hand-side ("group" in your case) from being immediately
used as the left-hand-side of a map. E.g., if you had defined

:iabbrev g group
:imap group <c-o>:echo "This is my group."<cr>

and you enter "g" and a space in insert mode, only the space would be
inserted into the buffer and the text "This is my group." would be
echoed on the command line.

There is the <unique> flag for maps and abbreviations (see

:help :map-<unique>

), which prevents you from redefining/overwriting a map or abbreviation,
though it seems a map can still be overwritten by an abbreviation and
vice versa.
