Oct 22, 2023 at 12:55 | comment | added | Martin Sleziak | I have replaced the dead link nbl.fi/~nbl4075/sts19cat.pdf with the link I found on this website. Most likely, it is the same paper (the filename is the same and the linked paper agrees with the description given in the answer). | |

May 20, 2010 at 4:36 | comment | added | Mariano Suárez-Álvarez | If $S$ is a STS, then one can add an element to get $S'=S\cup\{\infty\}$ and define an operation $\star$ on $S'$ so that $\infty$ is the identity element, $x\star x=\infty$ for all $x$ in $S$, and $x\star y=z$ if $\{x,y,z\}$ is a block of~$S$. Then $(S,\star)$ is a loop, and its order is one more than $S$'s. That's why they index things funnily. | |
