- a(n) = Product_{i=2..n} phi(i)/bigomega(i).at n=18A066988
- Let S_k denote the sequence of numbers j such that A001222(j) - A001221(j) = k. Then a(n) is the n-th term of S_n.at n=24A261256
- Partial products of A029940 (Product_{d|n} phi(d)).at n=12A280132
- Multiply a(n) by the first digit of a(n+1) to get a(n+2). The sequence starts with a(1) = 1 and a(2) = 2.at n=31A300759
