Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to work out how I can get the set at specific index in a cross product without creating the whole product.

For instance:

I have array A of length 512

I also have a number that specifies how many times that array needs to be 'cross-producted' against itself.

This gives me a potentially huge set of sets. I need to be able to work out what the set is at a particular point, without iterating through the entire cross product creation procedure.

Anyone have any advice?
