I'm obviously missing something dramatic here.. I guess I don't even understand the Puzzle itself..?

Re1Ra1 Re2Ra2 Re3Ra3 Re4Ra4 Re5Ra5 Re6Ra6

Re2Ra2 Re3Ra3 Re4Ra4 Re5Ra5 Re6Ra6 Re1Ra1

Re3Ra3 Re4Ra4 Re5Ra5 Re6Ra6 Re1Ra1 Re2Ra2

Re4Ra4 Re5Ra5 Re6Ra6 Re1Ra1 Re2Ra2 Re3Ra3

Re5Ra5 Re6Ra6 Re1Ra1 Re2Ra2 Re3Ra3 Re4Ra4

Re6Ra6 Re1Ra1 Re2Ra2 Re3Ra3 Re4Ra4 Re5Ra5

You repeat the same value multiple times (eg "Re1Ra1"), which also implies you are missing some. The square has to contain 36 different entries.
