If each of these “settings” has only two states (on/off like a switch) then there are 256 possible combinations (2^8).

If each “setting” has ten possible states, then the number of configurations is one-hundred-million = 100,000,000 = 10^8.

If the eight “settings” have different numbers of states the problem is more complex but, as stated, the problem is ambiguous (or incomplete).

If each “setting” has an infinite range of possible states, then then an infinite number of combinations can occur.
