# double sum referring to a factorial

Posted 11 years ago
 Hi guys,I am trying to evaluate the sum_(j=1)^k (sum_(i=1)^(k-1) ( (i+j)! ))for, say, k=5, so that I have 20 elements in sum. I would like to have a list of all 20 elements which I could plot then.Could anyone help with the syntax?  Many thanks!! Dimi

 What is the code you have already?If you want a list, you can use Table instead of of Sum. The syntax is basically the same. Table produces a list of the elements which Sum would have added.

 Thanks, I understand. But the question rather refers to the procedure of generating a vector of (k-1)x(k) outcomes. So its not the problem of the syntax of a double sum, but rather the next step.

 Hi. There are some examples of how to solve these kinds of problems in the documentation for Sum:http://reference.wolfram.com/mathematica/ref/Sum.htmlI think the first step to solving the problem would be to write out the summations in this syntax.
