| Dec 6, 2023 at 23:40 | comment | added | Noah Wisdom | Since Arun's comment, Andrew Senger has shown $BP$ is not $\mathbb{E}_{2(p^2+2)}$ for odd primes, providing a negative answer in general. | |
| May 19, 2017 at 20:04 | comment | added | Arun Debray | Since this question was asked, Tyler Lawson has shown that at $p = 2$, $\mathit{BP}$ is not an $E_n$ algebra for $n\ge 12$, thus providing a negative answer to this conjecture at 2. | |
