Subject: A Collatz cycle scale
Collatz sequences can cycle when started from negative integers; I
don't know what the conditions are, perhaps Jeff Lagarias does. I
can't find any 12 note scales, but starting from -17 gives a 7 note
scale. It's CS,
and strictly proper, and might be fun for someone to play with who
wants a variant of 7-equal.
