 Pushing Numbers 2 (Posted on 2007-05-22)
Here is the first part of Pushing Numbers.

You need to make it so that all the numbers from 1 to 8 appear once in every row and column. You can only do that by "pushing" the columns down and the rows left. Each time you "push" a row or a column all the numbers in it move one block in the direction you have pushed it.
 6 4 8 6 8 7 1 3 1 2 5 6 7 4 2 8 5 4 2 2 7 5 3 7 5 3 1 3 3 8 4 7 5 6 2 1 6 3 1 6 1 4 7 8 2 5 4 3 4 5 2 1 7 2 1 3 6 4 8 7 8 6 5 8
Can you do it?

I'm not sure the formula for eliminating all the permutations of a series of vertical or horizontal moves in a row, but the major consideration, the numerator of the fraction would be 24!, as each pushing advances the strip by only one digit position, so a total of 24 pushes must be done.
