• a(n) = Sum_{i=1..n} binomial(i+1,2)^3.at n=7A085438
• Least hairpin family matchings with n edges that are both L&P and C&C whose leftmost edge is part of a hairpin.at n=10A284968
• Number T(n,k) of ordered set partitions of [n] into k blocks such that equal-sized blocks are ordered with increasing least elements; triangle T(n,k), n>=0, 0<=k<=n, read by rows.at n=49A285824
• Number of ordered set partitions of [n] into four blocks such that equal-sized blocks are ordered with increasing least elements.at n=5A285919
• Place n equally spaced points on each side of an equilateral triangle, and join each of these points by a chord to the 2*n new points on the other two sides: sequence gives number of vertices in the resulting planar graph.at n=15A366483
