Non-isomorphic 4-(48,5,λ) designs with PSL(2,47) as automorphism group are enumerated. It turns out that there are 12, 295, 1195 and 2368 pairwise non-isomorphic designs in this class, with λ equal to ...
Chromatic symmetric functions and combinatorial polynomials are central constructs in modern algebraic combinatorics, extending classical graph invariants into rich algebraic frameworks. Originating ...
