7 men, A B C D E F G are staying in a hotel for 15 days. Every day the men gather to dine round a circular table. No man is ever sat next to the same 2 neighbours on more than 1 day. Can you come up with a seating arrangement for the 7 men on the 15 days. There is a solution, but none of the men found it.
edit: to all the clever buggers, there are only 15 seats.
