THE CANTERBURY PUZZLES
—three marked to represent foxes and three to represent geese.
Place the geese on the discs 1, 2, and 3, and the foxes on the discs
numbered 10, 11, and 12.
Now, the puzzle is this. By moving one at a time, fox and
goose alternately, along a straight line from one disc to the next one,
try to get the foxes on 1,2, and 3, and the geese on 10, 11, and 12—
a goose. It also
prevents your moving a fox from 10 to 9, or from 12 to 7. If you
play 10 to 5, then your next move may be 2 to 9 with a goose,
which you could not have played if the fox had not previously gone
from 10. It is perhaps unnecessary to say that only one fox, or one
goose, can be on a disc at the same time. Now, what is the
smallest number of moves necessary to make the foxes and geese
change places ?
