%N First digit of n alphabetically.
%C Digits are decimal with names in English (see A000052). A134777(n)=A134778(n) iff n is a repdigit (n=A010785(m)), in which case a(n)=A010888(m), the repeated digit. a(n)=0 only for n=0. a(n)=8 iff n is a member of A011538.
%H Michael S. Branicky, <a href="/A134777/b134777.txt">Table of n, a(n) for n = 0..10000</a>
%e a(104) = 4 because the digits of 104 are 1 (one), 0 (zero) and 4 (four) and "four" occurs before both "one" and "zero" alphabetically.
