Yes - (2^n)^3 where n is the bit depth - either 8 or 16. If you're working from a 24 or 48bit base, then you need to divide these figures by 3 before applying the formula (which gives you 8 or 16).
If that's not sensible, 8 bit images have 2^8 colours per channel, which is 256 colours, so in combination we have 256^3 or 16,777,216 colours possible. This is the standard that jpegs use and the one referred to in the help.
Elements only works with 8/24bit images or lower, converting ones with higher bit depth ( 16/48 ) down to this value.
