Thanks, David. Something else to add to the collection: using complex numbers to represent the last dimension. Perfectly familiar with it in the context of 2-D coordinates, but (not thinking outside the box) didn't spot its scope for the state transition matrix.
I guess if you use fractional complex numbers you can fit 4 integers in each entry!
