Yes! That was, perhaps, the main point of the whole talk! The music is highly-structure in that it contains no repetition, at many levels.
1. No note is repeated. (It's a permutation)
2. The interval between all pairs of notes which are separated, in time, by k notes is different. (The Costas Property)
3. The difference between the the starting time between any two notes is different. (Using the Golomb Ruler for starting times)
Doing 1 & 2 requires the usage of a Costas Array, which we only know how to form thanks to a problem in SONAR - and requires Galois Field Theory to construct.
