• Discriminants of quintic fields with 2 complex conjugates (negated).at n=39A023684
• Cube root of A030683.at n=23A030684
• McKay-Thompson series of class 18e for the Monster group.at n=46A058543
• Take pairs (x,y) with Sum_{j = x..y} j = concatenation of x and y. Sort pairs on y then x. This sequence gives x of each pair.at n=35A070152
• McKay-Thompson series of class 36b for the Monster group.at n=46A112173
• Let spm(n) be the sum of all prime factors of n counted with multiplicities (A001414); sequence gives numbers n such that spm(n+spm(n)) divides both n and n+spm(n).at n=13A131564
• Expansion of Product_{k>=1} (1 + x^k)^k / (1 + x^(5*k))^(5*k).at n=22A285293
• Numbers in a hexagonal tiling (seen as concentric rings) which have exactly three neighbors whose difference from it is prime.at n=28A372223
