The notes Combinatorics of OEIS-A074060 sketch how combinatorial interpretations of Lagrange inversion OEIS-A134685 and the 2-restricted Stirling numbers of the first kind OEIS-A049444 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).
