 OFFSET 1,2 LINKS Jean-Marc Falcoz, Table of n, a(n) for n = 1..4816 EXAMPLE a(1) = 1 together with a single 1 forms 11; a(2) = 2 together with a single 2 forms 22; a(3) = 3 together with a single 3 forms 33; … a(101) = 101 together with a single 0 forms 1001; 102 is not in the sequence as no palindrome number can be formed with the set [0,1,2,d], d being any single digit a(354) = 1002 is in the sequence as 1002 together with a single 1 forms 10201; etc. CROSSREFS Cf.
