Where's the "Co"?

I was clearing out old files and I stumbled across notes from a class I took in high school. On one of the pages was written:

The Most Common Prefixes

Prefix              Meaning
pre-                 before
de-                  away, down
inter-               between, among
ob-                  against
in-                   into
mono-              alone,one
epi-                  upon
ad-                   to, towards
un-                   not
non-                 not
re-                   back, again
pro-                 forward, for
in-                   not
dis-                 apart, not
over-               above
sub-                 under
mis-                 wrong
trans-               across, beyond

At the time, I never thought anything about it, but coming to it today, what immediately struck me was the lack of the prefix co- which means together, jointly, mutually. I wonder if that reflected the culture of the times, or if it still would not show up today as one of the most important prefixes...?
