 OFFSET 0,1 COMMENTS First differs from A037195 at the ninth term. The letter "y" is here considered a consonant regardless of its usage in the word(s). The maximum number of distinct vowels that can occur in the English name of n is 5, which occurs for n in A058179. - Jonathan Vos Post, Jul 12 2011 LINKS Michael De Vlieger, Table of n, a(n) for n = 0..10000 EXAMPLE a(13) = 4 because the distinct consonants present in THIRTEEN are T, H, R and N. a(9) = 1 because N is the only consonant present in NINE.
