I am trying to find the number of integral solution to the given equation ↵
↵
**x1+x2+x3+x4=n** given that **x1>x2>x3>x4**↵
↵
But could not figure out any mathematical formula to it. If someone knows how to solve it please help↵
↵
↵
**UPD:** xi>=0 (all number are greater than or equal to zero)↵
↵
↵
Thanks
