On the messageboard in recent weeks, we've set a few challenges based on the data we're collecting as we build up the results archive on the website, and the fourth challenge has just been set.

Since the beginning of the 1970/71 season we have played 206 different clubs in competitive matches. This includes matches such as the George Ruffell Memorial Trophy, Will Mather Cup, Barassi Cup etc, but not pre-season tournaments such as those we've recently played at Amersham and Hillingdon.

Of those 206 clubs, we've played 39 twenty or more times. Can you guess them?

For clarity, clubs that merge are counted as separate clubs. Clubs that simply change their name are counted as one club.
