Summary: In this paper we present some combinatorial structures enumerated by the sequence A079500 in Sloane's Encyclopedia of Integer Sequences and determine simple bijections among these structures. Then we investigate the nature of the generating function of the sequence, and prove that it is not differentiably finite.
