Sep 23 at 19:22 comment added Tom Copeland In a comment to Dan's answer, I noted the occurrence of the compositional inversion partition polynomials of OEIS A133437 and A134685 in two papers. A134685 also occurs in "Möbius Inversion and Duality for Summations of Stable Graphs" by Zhiyuan Wang & Jian Zhou on pgs. 18 & 19 (arxiv.org/abs/2401.11717).

Dec 8, 2015 at 6:56 comment added Tom Copeland To the degree that the inverse pair can be represented by certain types of trees, Drakes' thesis "An inversion theorem for labelled trees ..." people.brandeis.edu/~gessel/homepage/students/drakethesis.pdf has some insights.
Jan 31, 2015 at 10:10 comment added Tom Copeland There is an intriguing tale told by He and Jejalla in "Modular matrix models" interweaving the compositional inversion of generating series as in free probability theory, matrix models, gauge field theory, Calabi-Yau geometry, the Klein modular invariant j-function, and some monstrous moonshine.
