Iterated power set applications generate a hierarchy of operads linking the permutative operad to triassociative, substitution, and composition operads, plus a new operad on relative simplicial complexes governed by join polyhedral products.
Simplicial spheres without large missing faces satisfy g-number lower bounds in terms of graph independence numbers, including g2 ≥ (1/2 − δ(d))f0 for flag spheres with δ(d) → 0 as d → ∞.
Proves gamma-positivity for Hilbert-Poincaré polynomials of Chow rings of matroids with complete and flag building sets, yielding combinatorial analogues of classical positivity conjectures and an explicit simplicial complex realizing the gamma-vector.

Lower bounds on the $g$-numbers of spheres without large missing faces
Simplicial spheres without large missing faces satisfy g-number lower bounds in terms of graph independence numbers, including g2 ≥ (1/2 − δ(d))f0 for flag spheres with δ(d) → 0 as d → ∞.
