Wow, the nerdsniping on this is something. Note, for my math, I failed to consider that entries wouldn't fit in one byte. Figuring out an encoding might help.

Wow, the nerdsniping on this is something. Note, for my math, I failed to consider that entries wouldn't fit in one byte. Figuring out an encoding might help. Laying out a sequence in blocks might also help overcome the speed difference between memory and storage. I'm not even really trying to delve into this, but it's tempting.
