Sure, I'll try.... the first rwx is the 4's place, the second rwx is the 2's 
place, and the third rwx is the 1's place... it's another 3 digit binary 
number overlaid on TOP of the exisiting permissions.

so, "group" sticky would be.

0 1 0

which gives us a 2.

"user" sticky would be a 1 0 0 or,  4, this is mostly used to make stuff run 
"setuid" by another user (usually root)

and "other" sticky (used by the /tmp directory..shows up as a t in the 
permissions list)  would be 0 0 1   or   1

rwsrwsrwt  would be what it would look like at 7777

I hope that makes more sense.
