• 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=28A125491
• Number of length 4 0..n arrays with each partial sum starting from the beginning no more than one standard deviation from its mean.at n=24A244792
• Numbers k such that k +- 2 and k +- 3 are all semiprimes.at n=31A382049
