Combinations of r from n without replacement is
c(n,r) = n!/(n-r)!r!
c(n,r) = 23!/20!3!
c(n,r) = 1771.
23 x 22 x 21 x 20/4 x 3 x 2 = 8,855 groups
45
Oh, absolutely! Let's take a moment to appreciate the number 23. You can split it into equal groups, like 2 groups of 11 and 1 group of 1. Remember, there are many ways to divide numbers, so feel free to explore and find the one that brings you joy.

It is 20/23.
There are infinitely many groups of 20 numbers that have a mean of 25. One example: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35
