Superclub, splitting, separating statements

We prove that superclub implies $\mathfrak{s}={\mathrm{\aleph }}_1$. More generally, superclub at a successor of a weakly compact cardinal implies ${\mathfrak{s}}_{\kappa }={\kappa }^{+}$. Based on this statement, we separate tiltan from superclub at a successor of a supercompact cardinal. We use Galvin’s property in order to separate tiltan from superclub at successors of both regular and singular cardinals.
