I have a mathematical question: how many combinations can be had from 12 numbers? I think this has to do with permutations. I'm asking this because

in music there are 12 basic notes of the scale and I was thinking about all the music that has been written so far...using these 12 notes ( including repeated tones).

Thanks for any info on this

I wouldn't know the correct answer if it bit me on the nose, so that negates any possibility of a fair contest...

And it is represented by the following:

A factorial is designated by a positive whole number followed by an exclamation point.

12!

Or

12*11*10*9*8*7*6*5*4*3*2*1

The value of a factorial is the product of all the numbers from 1 through the number of the factorial. (In your instance, the number 12)
Factorials are used in determining the numbers of combinations and permutations and in finding probability.
