%N Numbers divisible by the number of syllables in their (American) English name.

%C The name has no extra "and" syllables, as in 104 being in this sequence because "one hundred four" has 4 syllables (which divides 104) rather than "one hundred and four" which has 5 syllables.

%F {k such that A075774(k)|k}.

%e a(15) = 21 because "twenty-one" has 3 syllables, and 3*7 = 21.
