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.

Table of n, a(n) for n=0..104.

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.
