I just noticed that the 20x20 grid has some "00" entries; thus, time could be saved by not touching any of the grid entries 3 cells away. Same for the "01" entries.
The challenge, of course, is in finding these entries in the first place. :)
Multiplication is cheap, looking for zeros (or ones) would take much more time than the multiplications one could avoid, so it'd be a net loss (it could become a gain if longer sequences were to be considered; depends on the proportion of zeros in the grid and the length).
