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
Yes, 23 can be split into equal groups. In this case, 23 can be split into 1 group of 23, 23 groups of 1, or any other combination that results in an equal distribution of the number 23 among the groups.
The SOC system identifies 23 major groups of occupations.

If the given dimensions are in feet then 23 times 20 = 460 square feet
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

23/20 = 13/20
It is 20/23.
