How about numbers that are a multiple of the number of letters in
their own name...
a(n) = 4, 6, 12, 30, 33, 36, 40, 45, 50, 54, 56, 60, 70, 81, 88, 90,
100, 112, ...
Also, the above numbers divided by the number of letters in their name...
Ahh, I see this is already in the OEIS as A092320 and A126259, but
the first one erroneously omits 56, and the second is using "and" in the names.
For example, "one hundred and eight" instead of "one hundred eight".
In American English, the "and" should be left out, but I think
(correct me if I am wrong)
that in British English, the "and" should be left in. Perhaps a comment is in
order to clarify for each sequence, whether it conforms to American or
British English.
