Open, the site's label (OPEN; page last edited 20 January 2026). The site's commentary credits Odlyzko and Stanley [OdSt78] with explicit descriptions of $A(3^m)$ and $A(2\cdot3^m)$ for every $m\ge0$, which answer both questions for those $n$; the memorandum states them without proof, and they are recorded as a claimed partial claim on its claim page (Odlyzko and Stanley, 1978). Rolnick proved them for $m\ge1$, with growth of order $k^{\log_23}$, in a refereed paper, recorded as an accepted partial claim on his claim page (Rolnick, 2014). Moy's bound $a_k\le(1/2+\epsilon)k^2$ [Mo11] holds for every $n$ and fixes no sequence's growth, so it settles no instance and has no claim page. For every other $n$ both questions are open.
