233.--THE ECCENTRIC CHEESEMONGER.

To leave the three piles at the extreme ends of the rows, the cheeses

may be moved as follows--the numbers refer to the cheeses and not to

their positions in the row: 7-2, 8-7, 9-8, 10-15, 6-10, 5-6, 14-16,

13-14, 12-13, 3-1, 4-3, 11-4. This is probably the easiest solution of

all to find. To get three of the piles on cheeses 13, 14, and 15, play

thus: 9-4, 10-9, 11-10, 6-14, 5-6, 12-15, 8-12, 7-8, 16-5, 3-13, 2-3,

1-2. To leave the piles on cheeses 3, 5, 12, and 14, play thus: 8-3,

9-14, 16-12, 1-5, 10-9, 7-10, 11-8, 2-1, 4-16, 13-2, 6-11, 15-4.
