• Number of 5-valent trees with n nodes.at n=18A036650
• Number of squares (of another matrix) in the group GL(2,Z_n) described in sequence A000252.at n=21A068516
• 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=21A125491
