| Dec 7, 2016 at 0:02 | comment | added | Brendan McKay | The numbers $(-1)^{|\pi|-1}(|\pi|-1)!$ are coefficients of the Möbius function of the boolean lattice, so what you are doing is inverting some lattice function. Perhaps the details can be gleaned from Fedor's answer. | |

| Dec 6, 2016 at 22:35 | comment | added | Gerhard Paseman | This forum is a Question and Answer forum. It is not a problem forum, nor a place to entertain much discussion. The community hopes to build a database of well-written posts to help the mathematical communities of today and tomorrow. In my opinion (based on almost 7 years experience on this forum), your post could be improved to fit the needs of this forum by making the change. If you do not wish to post questions, that is up to you, but it is well written questions that are preferred here. Gerhard "MathOverflow Is Not A Catchall" Paseman, 2016.12.06. | |
| Dec 6, 2016 at 22:19 | comment | added | T. Amdeberhan | What if it is not a question? A claim that I'm convinced is true. Conjectures are open to proofs or disproofs. Aren't they? | |

| Dec 6, 2016 at 22:00 | comment | added | Gerhard Paseman | For clarity, please edit the post to include a question mark. For example, end the post with "Is this conjecture true?". That way we know what part of the post you wish to address, even after subsequent edits. Gerhard "Make Post Interpretation More Robust" Paseman, 2016.12.06. | |
