Are there reserved group names?

I was poking around at something else and noticed that "net rpc group
display users" and "net rpc group display nobody" failed with "Couldn't
list alias members", which are the same groups broken above.

I renamed the groups and now they are apparently working fine, both
locally and with usrmgr alike.

I can kind of understand why "nobody" wouldn't work (there's a nobody
user, and there are "nobody" entries in the local passwd and group files
[which I'm not using, but add to the problem matrix]). Users appears to be
treated as a built-in group tho. Further of interest, "admins" works fine
as a groupname, which conflicts with the built-in thinking. Immediate
thought that's left after all this: they are reserved names?
