The fab 4 in mod 12.
But what about the M operation? Is that the fifth Beatle? I suppose rotation could be Peter Best…
The amazing thing is that George and Ringo are hexachordally combinatorial. Who knew?
Excellent observations, all. It strikes me that there’s a joke to be made about The Clash being an all-interval tetrachord, but I’ll leave that for another day.
(BTW, for the record, Ringo is my favorite Beatle.)
