• a(n) = 6^n + n^6.at n=7A001594
• a(n) = 7^n + n^7.at n=6A001596
• a(n) = n^(n+1)+(n+1)^n.at n=6A051442
• 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=37A076980
• Triangle read by rows: T(n,r) = n^r + r^n (1 <= r <= n).at n=26A093898
• Positions where A163890 obtains distinct new values.at n=33A163891
• Numbers of the form x^y + y^x, 1 < x < y.at n=31A173054
• a(n)/ceiling(6^(n-7)) is the expected number of rolls of a fair 6-sided die in a game where the player starts at 0, advances the position by the outcome of the die's roll until exactly position n is reached. Positions beyond n are avoided by staying at the last visited position, but counting the rolls.at n=12A331944
• 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=41A385232
