Nicolaas Govert (Dick) de Bruijn (Dutch: [nikoːˈlaːs ˈxoːvərt də ˈbrœyn]; 9 July 1918 – 17 February 2012) was a Dutch mathematician, noted for his many contributions in the fields of analysis, number theory, combinatorics and logic. (Wikipedia).
Before christmas I showed you some sequences called de Bruijn sequences. They're designed to contain every combination of some numbers without any repeats http://youtu.be/iPLQgXUiU14 For example, this sequence 1111222212211212 contains every combination of 1 and 2 of length 4. So 1111 is
