Do some phyiscs, you'll soon realize a page long equation is not always right.
and where's your function electrichead? wanna give it a try..
go ahead and solve it smartypants
( i mean that most endearingly)

I give you all the respect for your equation.
I just don't know if it is correct or not, hence my statement.
I just know how many times I worked on a maths or physics problem thinking I was spot on only to find out how wrong I really was.

isn't that the beauty of mathematics though?
you can check whether it's correct or not. i know exactly what you mean, i've fell victim to stupid mistakes many times but..electrichead this isn't even a long equation. all you have to do is substitute the numbers.

Xi = {2,3} so as a function you could say X(0) = 2, X(1) = 3 and f(x) = X(x) where x is either 0 or 1.
so now you have S total things but the number of groups needs to be divisible by four yes?
put N to be the number of groups: then N % 4 = 0 and the % is the modulus which gives the remainder of N/4
umm you also got S = Sum of X_i from i = 1 to N.
there are alot of possible combos for the actual groups, there's no one formula to get all the x_i's as you've seen in this thread.
my suggestion to you though would be to look at different combos of different configurations of groups and forget about the ones that don't have N be a multiple of 4.
i'll break it down for you since i'm such a darl
N = number of groups
S = total number of things
X_i = number of objects in group i where i is a whole number from 1 to N and
S = Sum X_i i = 1 to N
N % 4 = 0
X(a) = 2 if a = 0 or X(a) = 3 if a = 1 and a can only equal 0 or 1
