I would also add a comment in A121064 that it is not clear how these 
numbers are arrived at. It looks to me like it is just plain wrong - 
maybe the author only looked at values up to 100. There might be some 
variant I don't see, however.

Hans, The best thing is to create a new sequence with your
values, and say "For another version see A161064",
and add cross-references between them. Presumably
Opao is using a different version of the spelling
of numbers in English (maybe he counts hyphens, or
doesnt't count hyphens, or says - as I do - one hundred and two,
with an and in it...)

All these sequences that depend on spelling of names for numbers are
ultimately unsatisfactory. But they often
appear on tests, which is why they are included in
the OEIS.
