| May 4, 2021 at 13:26 | comment | added | Nathaniel Johnston | Adding on to Wojowu's comment slightly: thanks to how fast $BB(n)$ grows, we know that the first several decimal places of this constant are $1.2236315$. The next (at least) 36000 decimal places depend only on the value of $BB(5)$, which we do not yet know. | |

| May 4, 2021 at 11:33 | comment | added | Wojowu | Since BB(5) is not known, probably 1/BB(1)+1/BB(2)+1/BB(3)+1/BB(4)+1/(our best bound for BB(5)) | |
