There is a 2 inch grid cube made up of 8 wire-frame cubes, each with wire where their edges should be and space in their middle and faces.
The quickest way to get from one vertex to the opposite vertex is 6 inches. How many such paths are there?
To generalize charlie's formula
For wire frame of dimensions axbxc
The formula is
This can be extended or contracted to more or fewer dimensions as well.
