Honestly, I do not understand what do you mean with that definition.
At a certain point I thought you mean
"start with a matrix n x k filled with ones and count
how many configuration can be obtained if every one can be
moved (added) to a neighbouring cell.

Hover, if that was the case, I would expect a symmetric table of result,
so I'm baffled.
Could you please give me a "for-dumbs" definition of the problem ?
