A note on binary arrays with a certain window property (Corresp.)
S. Ma · IEEE Transactions on Information Theory · 1984
For somers = 2^{mn}, there exist periodicr \times sbinary arrays such that allm \times nbinary matrices will appear in it. As two-dimensional versions of de Bruijn sequences, these kinds of arrays have possible applications in cryptography and the design of mask configurations for spectrometers.
