• Theta series of lattice D3 tensor D3* (dimension 9, det. 262144, min. norm 6).at n=19A033694
• n! * (fractional part of n-th harmonic number).at n=7A095998
• Triangle read by rows, related to A055129 (repunits in base k).at n=32A107893
• a(1) = a(2) = 1. For n >=3, a(n) = the a(n-2)th integer, among those positive integers which are missing from the first (m-1) terms of the sequence, below a(n-1) if such a positive integer exists. Otherwise, a(n) = the a(n-2)th integer, among those positive integers which are missing from the first (m-1) terms of the sequence, above a(n-1).at n=40A118627
