 OFFSET 1,2 COMMENTS Differs from A082776 at a(5). a(n) <= (10^A055642(a(n-1))+1)*a(n-1). If a(n-1) > 10 and the last digit of a(n-1) <= 4, then a(n) <= (10^(A055642(a(n-1))-1)+1)*a(n-1). LINKS EXAMPLE a(3) = 121 is a palindromic multiple of a(2) = 11 and contains two '1', all the digits of a(2). CROSSREFS Cf. A055642, A082776.
