So is ℵ0 a set or a cardinal number, or both? "the set ℵ0" or "ℵ0 is the cardinality of the natural numbers"

comment Splitting a sandwich and not feeling deceived
@VividD Yes, I believe so. A cuts all pieces the same so that if he is pointed to last, he still gets 1/n of the cake. However, this still has the same flaw as the "You Cut I Choose" method, in which A cannot plan to receive more than 1/n of the cake, while the first person chosen is guaranteed more than 1/n (because no one can cut cake that evenly).
