Extending some results of Malykhin, we prove several independence resultsabout base properties of $\beta\omega-\omega$ and its powers, especially theNoetherian type $Nt(\beta\omega-\omega)$, the least $\kappa$ for which$\beta\omega-\omega$ has a base that is $\kappa$-like with respect tocontainment. For example, $Nt(\beta\omega-\omega)$ is never less than thesplitting number, but can consistently be that $\omega_1$, $2^\omega$,$(2^\omega)^+$, or strictly between $\omega_1$ and $2^\omega$.$Nt(\beta\omega-\omega)$ is also consistently less than the additivity of themeager ideal. $Nt(\beta\omega-\omega)$ is closely related to the existence ofspecial kinds of splitting families.
