Using the generalized L-out-of-M-out-of-N method that I posted Sunday,
here's some 5-tone three-term index examples where a*T = c; that is
the product of the smallest stepsize and the Tribonacci constant
equals the largest stepsize.

This method, while still in need of some "finishing", could be seen as
a counterpoint to the generalized two-term (stepsize) scales after
Kornerup, where an internally consistent standard that is tethered to
neither JI nor ET exists for any arbitrary three-term (stepsize) scale
as well... and "trivalence", while a special and frequent condition
here, is not a synonymous one.
