    An interesting concept, however it mainly makes apparent a 4-byte seed isn't sufficient to generate all conceivable board set-ups: rather than some 2^108 it will produce no more than 2^32 of them, a mere drop in the ocean. BTW: the OP mentioned trillions, not sure he meant that in the long or short scale of ways (see here[^]) :)

    True, but 2^32 ought to be enough for anybody :)

      And if all the cells on the edge can only have 5 different values, you can combine each corner cell with an edge cell, giving 4 * 15 possibilities (6 bits), and then you have 5^12 possibilities left for all other edge cells together which fits in 28 bits, giving 85 bits in total.

      I don't really follow what you said (e.g., what do you mean by "combine each corner cell with an edge cell"?), but keep this in mind:

      The OP wrote:

      some specific cells (Corner cells) can have only 3 of those values

      We already know each corner cell can only use 3 (rather than 8) values. I didn't just pick an arbitrary value, if that's what you are implying (I honestly don't know what you mean).

          I'd say nobody will ever need more than 640KB of RAM. :rolleyes:

              It wasn't a very obscure joke, for a site like this :)

                If the corner cells can have 3 values and the middle cells 8, then I see the pattern "they can hold as many values as there are adjacent cells". The OP did not say it, but he's been a bit slow in providing information anyway. It's just a guess, and that's why there is an if near the beginning of my post. The combining is .. just combining. Combine a corner cell (3 states) with an edge cell (might have 5 states) to get 15 in total, which is very close to a power of 2.

                      for 6*6 cells with no more than 8 states each, not really compression, is it? :)
