[R] condition in triple summation

[jim holtman]

Not sure I understand what your condition 'i > j > k' means in the context
of where each of the values is 1:3.  The only value that meets that
condition is i =3, j=2 & k=1, but you said exclude any cases where the
values were equal to 1.

Can you clarify with an example what you mean.

Tell me what you want to do, not how you want to do it.
