# How can I plot this function with multiple indices?

$$\prod_{p=4}^{10}\prod_{q=1}^{p} \Big[|\sum_{j^p_q=4}^{p+1} (i Sin \theta)^{|p-j^p_q|}|\Big]$$

The summation is indexed by $$j^p_q$$, where p and q are defined by the product rule. I was planning to put a for loop for p and within it a for loop for q and then use continuous multiplication within the loop.

P.S> This is my firs time posting a question. Pardon if it looks shabby.
