• Number of planted planar trees (n+1 nodes) where any 2 subtrees extending from the same node are different.at n=14A032027
• Numbers n such that sum of consecutive primes to p is pandigital (includes all 10 digits exactly once).at n=0A049443
• Terms in A006512 containing the digit "6" at least once, such that changing every "6" to a "9" and vice versa yields a larger term in A006512.at n=26A123211
