• Numbers k such that 93*2^k+1 is prime.at n=35A032396
• Number of partitions of n into parts not of the form 23k, 23k+8 or 23k-8. Also number of partitions with at most 7 parts of size 1 and differences between parts at distance 10 are greater than 1.at n=44A035996
• Primitive abundant numbers version 2 (abundant numbers all of whose proper divisors are deficient numbers) and increasing any prime factor in the prime factorization gives a non-abundant number when factored back.at n=42A335557
• Primitive nondeficient numbers satisfying a stronger condition that compares abundancy with related numbers as detailed in the comments.at n=24A352739
• Numbers that are abundant (A005101) and have no Zumkeller divisors.at n=4A376879
• Numbers which can be written in precisely one way as sum of a subset of their proper divisors but are not Zumkeller numbers, i.e., have no subsets of their divisors such that the complement has the same sum.at n=3A378519
• Symmetric difference of the primitive non-deficient numbers and the primitive Zumkeller numbers.at n=20A378538
• Numbers that are primitive non-deficient, but not primitive Zumkeller.at n=4A378656
