EXAMPLE

Note that A052360(373373) = 64 and A005589(373373) = 56.

Sequence A052362 uses A052360 which also counts spaces and dashes, therefore "twenty-one" 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

PROG

(PARI) m=0; for(n=0, 2e6, if(m<A005589(n), m=A005589(n); print1(n", "))) \\ M. F. Hasler, Aug 12 2020

(Python)

from itertools import count, islice

from num2words import num2words as n2w

def f(n): return sum(1 for c in n2w(n).replace(" and", "") if c.isalpha())

def agen():

    record = 0

    for n in count(0):

        value = f(n)

        if value > record: yield n; record = value

        n += 1

print(list(islice(agen(), 40))) # Michael S. Branicky, Jul 12 2022
