• Maximum fixed points under iteration of sum of cubes of digits in base n.at n=23A226026
• Number of length-n 0..7 arrays with no repeated value differing from the previous repeated value by one or less.at n=4A269605
• Number of length-5 0..n arrays with no repeated value differing from the previous repeated value by one or less.at n=6A269608
• Numbers k such that (68*10^k - 257)/9 is prime.at n=22A288149
• a(n) is the smallest positive integer not yet in the increasing sequence that is obtained when the largest digit from a(n-1) is deleted and the remaining digits are permuted such that no digit in a(n) has the same position it had in a(n-1) (counting from left to right). No repeated digits allowed; a(1)=10.at n=19A302095
