| Aug 9 at 14:42 | comment | added | Andreas Blass | This argument essentially shows that sep$(\kappa)$ is the smallest $\lambda$ such that $2^\lambda\ge\kappa$. (This characterization of sep$(\kappa)$ would have been my comment on the question, but I put it here because you've provided all the ingredients of the proof.) | |
