COMMENTS

Old name was: a(n) = n-th term of A026600 that is not a 3.

This sequence equals the standard form of A057215, i.e., a(n) = A057215(n)+ 1 for all n. This follows by noting that this sequence equals the [123->12, 231->21, 312->12]-transform of three-symbol Thue-Morse A026600. - Michel Dekking, Apr 18 2019
