On the edge of our plenum you see a special arrangement of zeros and ones made of wood:
Think of any sequence of six digits that contains only zeros and ones (e.g. 100110). Find your made-up sequence on the edge of the plenary. Can you only find it once?
This wooden zero-one sequence is an example of a so-called de Bruijn sequence. The Sanskrit artificial word Yamātārājabhānasalagā, which we have chosen as a name, also describes a de Bruijn sequence, here of short and long syllables.
