All-distances-twice rows
Consider a tone-row f and determine the list
(d1,…,d12) of distances between consecutive tones of f,
i.e. di is the distance
of f(i) and f(i+1) for i∈ {1,…,11} and d12
the distance of f(1) and f(12). If
each distance from {1,…,6} occurs exactly twice in
(d1,…,d12), then f is an
all-distances-twice row.
