When we start getting to 3 photon combinations, 4 photons onwards to 1.92 × 10 ^ 28 number of systems, we Still a limited number, in that there's only 1.92 × 10 ^ 28 numbers to play
around with, but far more combinations than there are
stars (or to put it another way, you could have unique combinations being
presented to a person as fast as they could perceive it for their entire life, and you could probably do the same thing with every
other person, without having any duplicate combinations between people.
