Appears in sequences
- a(1) = 3, a(n) = smallest multiple of a(n-1) such that 10*a(n) + 1 is prime.at n=20A089325
- a(1)=2, a(n+1)=a(n)*(n-th digit of the sequence or 10 in case of digit '0').at n=16A210579
- Sequence starting with a(1) = 2 and always extended with the product "n-th digit * n-th term". When the product is = 0, we don't extend the sequence with 0 but with the smallest integer not yet present.at n=16A337109
