# Fundamental constants and equations

How many independent fundamental physics constants are there that are not expressed in terms of other constants? What are they? I assume they would include the speed of light, c, and ε0, but μ0 can be left out, the gravitational constant, Plank's constant, fundamental particle masses and charges. Is there a clearly identified list?

How many fundamental physics equations are there that can't be derived from other equations or are not special cases of other equations? Is that something that can be clearly identified?
