Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Integers whose base-10 representation (Bm,...,B1,B0) is such that the polynomial f(x) = B0 + B1*x + ... + Bm*x^m is irreducible over the ring of integers, 0 <= Bi <= 9.
%F Integers in A000027 but not in A267509.
%e 11 is a member as f(x) = B0 + B1*x = 1 + 1*x has no factorization other than the trivial one, i.e., 1*(1+x), hence f(x) is irreducible over the ring of integers.
%e 114 is a member as f(x) = B0 + B1*x + B2*x^2 = 4 + 1*x + 1*x^2 = 4 + x + x^2 is irreducible over the ring of integers.
