I have a question regarding CSP. So, in this (

http://sqfunnub.wixsite.com/42pnpls/csp-guide) document Lakshay (i think it is) mentioned that he uses this rule for reference schemes: "The first edge position for a shape on top is the leftmost (CCW-est) edge in the biggest group of edges of that shape. The sequence goes clockwise from there, numbering each edge position as 2nd, 3rd, 4th, ...., n where n is the number of edges the shape has." If you have 6 edges on bottom, do you start on top with the 2 edges, or do you start with the largest group of edges (basically start on bottom)? Thanks to anybody who takes the time to answer my question!!
