 An example of the next possible binary "square" de Bruijn torus, "(256,256;4,4)2" (abbreviated as "B4"), has been explicitly constructed.The image on the right shows an example of a "(256,256;4,4)2" de Bruijn torus / array, where the zeros have been encoded as white and the ones as red pixels respectively.The paper in which an example of the "(256,256;4,4)2" de Bruijn torus was constructed contained over 10 pages of binary, despite its reduced font size, requiring three lines per row of array.
