• McKay-Thompson series of class 26a for Monster.at n=35A058598
• Amicable triples: numbers such that sigma(x) = sigma(y) = sigma(z) = x+y+z, x<y<z. We order these triples according to the common value of sigma. Sequence gives y numbers.at n=4A125491
• Amicable triples: numbers such that sigma(x) = sigma(y) = sigma(z) = x+y+z, x<y<z. We order these triples according to the common value of sigma. Sequence gives z numbers.at n=6A125492
• 1, followed by list of numbers n such that the number of strong primes and the number of weak primes are equal at the n-th prime.at n=40A175102
• Number of nondecreasing strings of numbers x(i=1..8) in -n..n with sum x(i)^3 equal to 0.at n=20A188282
• Let x(1)x(2)...x(q) the decimal expansion of the numbers k having exactly q distinct prime divisors p(1) < p(2) < ... < p(q). Sequence lists the numbers k such that p(1)/x(q) + p(2)/x(q-1)+ ... + p(q)/x(1) is an integer.at n=29A235153
• Numbers that belong to at least one amicable tuple.at n=34A255215

• Numbers k such that omega(k) = 5 and the largest prime factor of k equals the sum of its remaining distinct prime factors, where omega(k) = A001221(k).at n=24A383729
• Numbers z such that there exist two integers 0<x<=y<=z such that (x^2/sigma(x)^2 + y^2/sigma(y)^2 + z^2/sigma(z)^2) * (x + y + z)^2 = x^2 + y^2 + z^2.at n=8A385749
• Numbers z such that there exist two integers 0<x<=y<=z such that sigma(x)*sigma(y)*sigma(z) = (x + y + z)^3.at n=10A386010
