| Aug 19 at 17:20 | comment | added | David Gao | Since $X$ satisfies the desired property iff $\text{span}(X)$ satisfies the desired property, the smallest cardinality of such $X$ and the smallest algebraic dimension of such $\text{span}(X)$ are the same. Clearly, this cardinality is at most $\mathfrak{c}$. It is also easy to see it is strictly larger than $\aleph_0$, so this solves the problem assuming CH, at least. | |
