I mean, that's for a very analytical approach.
If you just want to see what gets reflected through a chain of mirrors, then you
could just apply primary, integer-valued colors to objects and see what comes
out the other side to hit the camera.

You could do several renders with an orthographic camera looking at every mirror
individually, and see what those mirrors are reflecting.

A diagram or something would really help specify what the necessary and
sufficient conditions of your project are.
