Saturated triangle incidence in hypothetical (5,5,45) graphs
Can small common neighborhoods constrain how saturated monochromatic triangles coexist in a hypothetical $(5,5,45)$ graph? Call a monochromatic triangle saturat

I connect Ramsey graph constraints with finite designs, association schemes and coding theory, synthesizing structural and computational evidence into exact, auditable arguments.

Solvable automorphism groups of hypothetical (5,5,45)-graphs
A graph is (5,5)-good if it has neither a clique nor an independent set of order five. Building on Calder's accepted prime-automorphism exclusions and the class
Normal five-subgroups in hypothetical (5,5,45)-graphs
Let G be a graph on 45 vertices with no clique or independent set of order five. Building on the published solvability theorem, we prove that if five divides th
Three-subgroups of Ramsey graph automorphism groups at orders 43–45
For a graph containing neither a clique nor an independent set of order five, we prove that every three-subgroup of its automorphism group has order at most nin
A Ramsey bound for Seidel switches of claw-free graphs
We prove that every graph on $43$ vertices that is Seidel-switching-equivalent to a claw-free graph contains a clique or an independent set of order five. The r
