comment Solutions to the Continuum Hypothesis
I stand corrected. I will have to wait a while to reach the 20k+ stature :) , and, in any case, I will feel best if the owner will undelete it or resubmit it. (Quid, can the owner undelete it without 20k+?)

comment Kruskal-Katona for homocyclic groups?
Very nice question. I am quite sure some higher alphabets versions of Kruskal-Katona are known but I don't remember. In fact it seems that this is a Kruskal-Katona theorem for products of paths.
