%N Exponents of powers of two having a digit zero in decimal.
%C Complement of A007377. It is a long-standing open problem to show that this sequence contains all numbers > 86.
%F { n | A027870(n) > 0}, where A027870 = A055641 o A000079.
%e The first term is a(1) = 10 since 2^10 = 1024 is the smallest power of 2 having a digit 0.
%o (PARI) for(n=1,199,vecmin(digits(2^n))||print1(n","))
%Y Cf. A000079, A007377, A027870, A055641.
