Sadly, I can only give the Google answer to this one:

I don't remember the details, but the possible transitions between particles have the same pattern as the valid codes in a Reed-Solomon code. So any particle is possible, but the transitions seem to have been error-corrected? I remember thinking it was a little flimsy at the time.
