Is you copy of 'bc' broken, or are you figuring in hex :-)

If all users were at the 16 character name limit you have about
16,000 users in a group, and about 32,000 if you limited them
to 8 character names.  This is just a rough 'back of the envelope'
figure not counting commas, etc, or the actuall bytes in 256K - I
just used 256,000 as the number.
