 OFFSET 0,3 COMMENTS a(n) = 0 for almost all n. - Charles R Greathouse IV, Oct 02 2013 More precisely, a(n) = 0 asymptotically almost surely, i.e., except for a set of density 0: As the number of digits of n grows, the probability of having no zero digit goes to zero as 0.9^(length of n), although there are infinitely many counterexamples. - M. F. Hasler, Oct 11 2015 LINKS Reinhard Zumkeller, Table of n, a(n) for n = 0..10000 FORMULA a(A011540(n)) = 0; a(A052382(n)) > 0. - Reinhard Zumkeller, Apr 25 2012 a(n) = A262188(n,0). - Reinhard Zumkeller, Sep 14 2015 a(n) = 0 iff A007954(n) = 0. - M. F. Hasler, Oct 11 2015 a(n) = 9 - A054055(A061601(n)). - Robert Israel, Jul 07 2016 EXAMPLE a(12) = 1 because 1 < 2.
