I want to know "how we can find the algebraic dimension(the cardinal number of the Hamel basis) for $\ell^p$ spaces." What can we say about $\ell^p(I)$, where $I$ is an infinite set?\
Moreover, for any given cardinal number $\alpha \neq \aleph_0$, is there a Banach space $X$ that its algebraic dimension equal $\alpha$?
