EXAMPLE

Note that A052360(373373) = 64 and A005589(373373) = 56.
Sequence A052362 uses A052360 which also counts spaces and dashes, therefore "twentyone" is in that sequence but not in this one: it uses one more character ('') but has the same number of letters than "seventeen".  M. F. Hasler, Aug 12 2020
