 OFFSET 0,2 COMMENTS The digits of each term a(n) are a permutation of those of the corresponding term A005151(n). - Chayim Lowen, Jul 16 2015 LINKS Table of n, a(n) for n=0..24. FORMULA After a while sequence has period 2. EXAMPLE To get the term after 311322, we say: two 3's, two 1's, two 2's, so 232122.
