 OFFSET 1,2 COMMENTS The sequence starts with a(1) = 1 and was always extended with the smallest available integer not yet present in the sequence. This is the lexicographically first sequence with this property. LINKS Lars Blomberg, Table of n, a(n) for n = 1..10000 EXAMPLE 1 + 3 (the next digit) = 4 (even); 3 + 4,2,5 (the next 3 digits) = 14 (even); 4 + 2,5,7,8 (the next 4 digits) = 26 (even); 2 + 5,7 (the next 2 digits) = 14 (even); ... 9 + 1,1,1,3,3,0,2,1,1 = 22 (even); ... 0 + (no digit) = 0 (even).
