| Jul 14, 2019 at 9:19 | comment | added | Andrej Bauer | @NikolaiMnev: I could never manage that, Facebook actively tries to impose things that are not "good discussion". I stopped using it a year ago, never looked back. | |
| Jul 14, 2019 at 9:18 | comment | added | Nikolai Mnev | @AndrejBauer If you maintain a good friend list than a good discussion can be even on Facebook | |

I would recommend that you summarize the conclusions of the Facebook discussion here, either by editing your question or by posting an answer to your own question. | |

| Jul 11, 2019 at 13:35 | comment | added | Nikolai Mnev | @darijgrinberg I am using usual simplicial topology conventions, attributing to simplicial degeneracy operation but permuted. Meaning add one to all elements on j places with $\eta(j) > \eta(i)$ and put as $i+1$-th element $\eta(i)+1$. it is right the same what Fedor says , but in simplicial algebra $\frac{1}{2}$ looks very foreign :) | |
| Jul 11, 2019 at 12:46 | comment | added | darij grinberg | @NikolaiMnev: If it's $\eta(i)+1$, then what about Fedor's comment? There is no canonical monotone reordering when two entries are equal. | |

| Jul 10, 2019 at 17:01 | comment | added | Nikolai Mnev | @FedorPetrov right. Sorry was fighting with phone replying. Snd finnsly killed the comment. | |
| Jul 10, 2019 at 16:55 | comment | added | Fedor Petrov | $s_3(51243)=612354$, right? | |
| Jul 10, 2019 at 16:33 | comment | added | Fedor Petrov | In $s_i$ you mean that we insert something like $\eta(i)+1/2$? $\eta(i)+1$ may be already in the permutation. | |
