On this bit, in some code I reckoned sequences like that as
"smaller" in the sense that values are smaller than the indices.
It choose between styles of plotting: a(n) as a colour for small,
or a(n) as a location for big.  But I never worked out whether to
be strictly a(n)<n, or after a few initial values, or even just
"mostly so".
