| Mar 23, 2020 at 23:59 | comment | added | Gerry Myerson | Also, the question has been discussed here on MO: mathoverflow.net/questions/241569/… where Zhi-Wei Sun gives the reference Antonio Filz [J. Recreational Math. 14(1982), p.64] and Max Alekseyev gives the reference oeis.org/A051252 – oh, and it is in Guy's book, in the section (C1) on Goldbach's conjecture, with the attribution to Filz. | |
| Mar 23, 2020 at 23:47 | comment | added | Gerry Myerson | I can't find it in Guy's book. A recent paper is Chen, Fu, and Guo, From a consequence of Bertrand's postulate to Hamiltonian cycles, arxiv.org/abs/1804.07104 The authors prove the conjecture holds for infinitely many $n$. They seem to be unaware of previous discussions of the conjecture. | |

corrected terminology

| Mar 23, 2020 at 21:53 | comment | added | Santi Spadaro | I meant "Hamiltonian". Thanks for pointing that out. | |
| Mar 3, 2020 at 7:36 | comment | added | OHO | Surely you don’t meen Eulerian? For example, $G_4$ isn’t Eulerian as it has many odd degree vertices. | |
