Appears in sequences

• Consider all integer triples (i,j,k), j,k>0, with i^3=j^3+binomial(k+2,3), ordered by increasing i; sequence gives k values.at n=26A054236
• McKay-Thompson series of class 26B for Monster.at n=39A058597
• Smallest number with persistence n for the sort-and-subtract-sequence.at n=25A065641
• Numbers k such that sigma(k) = phi(k*bigomega(k)).at n=26A068400
• Numbers n such that sigma(n) = 6*phi(n).at n=15A104900
• Expansion of q^(-1) * (chi(-q^13) / chi(-q))^2 in powers of q where chi() is a Ramanujan theta function.at n=39A128518
• Numbers n such that 5^n-6 is prime.at n=25A165701
• Number of ways to place 2 non-attacking wazirs on an n X n toroidal board.at n=19A201236
• Numbers k such that k = rad(k) * sopfr(k), where rad(k) is the squarefree kernel of k and sopfr(k) the integer log of k.at n=32A280935
