• a(n) = (n+1)*binomial(n+1,4).at n=23A027764
• a(n) = n^2*(n-1)*(n-2).at n=25A047929
• Consider the solutions to k = a+b = x*y and a*b = k*(x+y) where k, a, b, x, and y are all positive integers, ordered by increasing k and, in case of ties, by increasing x. Sequence gives values of a*b.at n=20A057421
• Number of integer compositions of n whose leaders of strictly decreasing runs are strictly increasing.at n=34A374762
• Numbers k of the form 4u+2 such that sigma(k) AND 3*k = 3*k, where AND is bitwise-and, A004198.at n=0A388023
