• a(n) = 3^n + n^3.at n=12A001585
• Leyland numbers: 3, together with numbers expressible as n^k + k^n nontrivially, i.e., n,k > 1 (to avoid n = (n-1)^1 + 1^(n-1)).at n=40A076980
• Numbers of the form x^y + y^x, 1 < x < y.at n=34A173054
• Number of subsets of {1,2,...,n-12} without differences equal to 2, 4, 6, 8, 10 or 12.at n=65A224813
• Numbers n such that the result of n multiplied by the reversal of n can be split into two numbers a and b of equal length (if the length is odd a leading zero is allowed), where a + b equals n (b can also have a leading zero).at n=34A259316
• Numbers that can be written as s^x + t^y, with 1 < s < t and {s,t} = {x,y}; that is, are of the form s^s + t^t or s^t + t^s.at n=44A385232
