what rhythm is this?

[speedcuber]

go to 0:36 here:

i am a big fan of identifying polyrhythms and other crazy stuff but this is sort of an unsolvable riddle to me. i already asked a friend who is a drummer and has great knowledge of crazy rhythms and since he neither recognised anything so i thought i would ask this forum although its not a piano-related question. (sry for that)

a good hint could be the flute at 1:26 because its notes are all of the same length.

Worked it out to the following:

3333 222222 33 | 33 222222

Alternately the groupings can be summarized: subdivision_group(number_of_iterations)
3(4), 2(6), 3(2) | 3(2), 2(6)


I would interpret the flute at 1:26 as playing a tuplet 2 over 3.
