• a(n) = A047848(7,n).at n=10A047855
• Numbers n such that s[n], p[n] and s[n]+p[n] are all prime numbers, where s[n] is the sum of digits of n and p[n] is the product of digits of n.at n=6A065439
• A Jacobsthal sequence (A078008) to base 4.at n=20A092900
• Table T(n,k) = ceiling(10^n/(10^k-1)), n >= 0, k >= 1, read by antidiagonals.at n=55A176088
• A base-3/2 sorted Fibonacci sequence that starts with a(0) = 0 and a(1) = 1. The terms are interpreted as numbers written in base 3/2. To get a(n+2), add a(n) and a(n+1), write the result in base 3/2 and sort the "digits" into increasing order, omitting all zeros.at n=21A305753
