**Reiny**, Monday, June 7, 2010 at 9:16pmFirst lets look at the number of combinations (order won't matter) to go the 10 steps

Behind it I will then do the number of permutations

2 2 2 2 2 ---- 1

2 2 2 2 1 1 --- 6!/(4!2!) = 15

2 2 2 1 1 1 1 --- 7!/(3!4!) = 35

2 2 1 1 1 1 1 1 --- 8!/(2!6!) = 28

2 1 1 1 1 1 1 1 1 --- 9!/(1!8!) = 9

1 1 1 1 1 1 1 1 1 1 --- 1

total = 1+15+35+28+9+1 = 89
