1,6,11 are the optimal non-overlapping channels. Any channels seperated by at least 5 don't overlap, so if someone is using 3 in a given area, 8 would be the next available non-interfering channel.
For 802.11a, there are 12 non-interfering channels. These are numbered in 5 MHz intervals, so the channel numbers hop by 4s.
