0. Mr Green buys four cinema tickets for himself, his wife and their best friends Mr and Mrs White. Mrs Green is a rather large lady who must sit in a wider aisle seat. In the interest of marital harmony each husband must sit next to his wife. The tickets are for seats, A1, A2, A3 and A4 shown on the plan below. The outing was so enjoyable that all three couples decide to repeat the experience the following week but this time Mr Green buys tickets for seats A1, A2, A3, A4, B1 and B2. Assuming that the usual restrictions about where they can sit still apply, work out the number of ways in which Mr Green can allocate the tickets. B1 B2 B3 B4 B5 B6 B7 Aisle A1 A2 A3 A4 A5 A6 A7​
