 OFFSET 1,2 LINKS Table of n, a(n) for n=1..68. FORMULA a(n) = A011539(n - 44) for n >= 53. - David A. Corneth, Jul 11 2020 EXAMPLE a(10) = 31 which has the largest digit (in base 10) 3. So a(11) must contain a 3 and be larger than 31. The least positive integer with these properties is 32. So a(10 + 1) = a(11) = 1. - David A.
