Next term contains a non-decimal character if such characters are chosen to represent digits > 9, where "digit" means the coefficients in N = Sum_{k>=0} d_k * b^k. This isn't possible here, but digits 0, 10, ..., 13 could be represented, e.g., using 00, 10, ..., 40. This would not affect a(0)..a(10), which don't have a digit 0. - M. F. Hasler, Jun 25 2018

(PARI) apply( a(n)=fromdigits(digits(2^n, 14)), [0..10]) \\ This yields Sum d[k]*10^k where d[k] are the base 14 digits. To get strings possibly containing letters 'A'..'D' replace fromdigits(...) by Strchr(apply(d->48+d+(d>9)*7, ...)). - M. F. Hasler, Jun 25 2018
