The notes Combinatorics of OEIS-A074060 sketch how combinatorial interpretations of LaGrange inversion and the 2-restricted Stirling numbers of the first kind provide a combinatorial construction for the array OEIS-A074060 (Graded dimension of the cohomology ring of the moduli space of n-pointed curves of genus 0 satisfying the associativity equations of physics).

 Short Note on Lagrange Inversion is an addendum to OEIS-A134685.
