EXAMPLE
Given the positions marked thus:
a b c
d e f
g h i j k l m
n o p q r s t
u v w x y z 0
1 2 3
4 5 6
there are 12 ways to make two moves, viz.,
(1) e jumps over j, then h jumps over i;
(2) e jumps over j, then x jumps over q;
(3) e jumps over j, then l jumps over k;
(4) o jumps over p, then d jumps over i;
(5) o jumps over p, then 1 jumps over w;
(6) o jumps over p, then r jumps over q;
(7) 2 jumps over x, then j jumps over q;
(8) 2 jumps over x, then v jumps over w;
(9) 2 jumps over x, then z jumps over y;
(10) s jumps over r, then f jumps over k;
(11) s jumps over r, then p jumps over q;
(12) s jumps over r, then 3 jumps over y.
