In this method a magic square is "multiplied" with a medjig square to create a larger magic square. The namesake of this method derives from mathematical game called medjig created by Willem Barink in 2006, although the method itself is much older.[citation needed] An early instance of a magic square constructed using this method occurs in Yang Hui's text for order 6 magic square.[citation needed] The LUX method to construct singly even magic squares is a special case of the medjig method, where only 3 out of 24 patterns are used to construct the medjig square.[citation needed]
