Possible permutations, how to work out the maths

I am interested in understanding how to calculate possible permutations. For example for a 24bit MAC address (made up) ad:ba:32:d5:f0:dd. I believe the highest possible value per octet would be FF. So the highest possible value for the last 3 octets would be FF:FF:FF, so would that be 16 to power of 16? or 16 x 16? As you may have guessed my maths is rather lacking so I would like to understand how this would work.



Possible Values Up To F

How to find $\lim_{h\rightarrow 0}\frac{\sin(ha)}{h}$ without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
