- Numerator of Hermite(n, 13/14).at n=5A159512
- For each permutation of {1,2,...,n} one or more integers might not be part of any longest increasing subsequence (LIS) of that permutation. The sequence lists the number of permutations for which ceiling(n/2) is not part of any LIS. For example, if n=4, 2 is not in any LIS of the two permutations (1342) and (3421).at n=8A168502
- Antiharmonic numbers using anti-divisors: numbers n such that sigma*(n) divides sigma*_2(n), where sigma*(n) is the sum of anti-divisors of n and sigma*_2(n) the sum of squares of anti-divisors of n.at n=19A192286
- Number of integer partitions of n whose run-lengths are not unimodal.at n=50A332281
