• a(n) = number of (s(0), s(1), ..., s(n)) such that s(i) is a nonnegative integer and |s(i) - s(i-1)| <= 1 for i = 1,2,...,n, s(0) = 2, s(n) = 5. Also a(n) = T(n,n-3), where T is the array in A026323.at n=10A026328
• Odd numbers which take a record number of steps to reach {1, 9, or 33} under iteration of the map described in the comments section of A135730.at n=35A261674
