N1100 Four Switch Stack Cabling

I've checked the manuals and Google but can't find an answer for what seems to be a simple question....

If I have 4 x N1100 switches (N1124/48) in a stack how would I cable them up?

I create a ring 1-2-3-4-1 with 2 of the SFP ports on each switch. But what about the other 2 SFP ports?

Can create another ring say, 1-3-2-4-1? Or is stacking limited to a single ring using just 2 of the SFP ports?
