| Aug 30, 2019 at 14:52 | comment | added | Matthias Künzer | Yoneda is not a generalisation of Cayley. A possible generalisation of Cayley is C -> (Set), X |-> Ob(C/X). See Freyd, Scedrov, "Categories, Allegories", 1.272. (Why is this not an interesting question when so far only Freyd and Scedrov had the answer?) | |

| May 1, 2011 at 23:50 | comment | added | timur | Is "yoneda" a person's name? | |
| May 1, 2011 at 23:28 | comment | added | Thierry Zell | @Abdelmalek: according to wiki, the theorem that says that a group G is isomorphic to a subgroup of Sym(G). | |
| May 1, 2011 at 23:13 | comment | added | Abdelmalek Abdesselam | which theorem of Cayley are you thinking of? his collected mathematical works make a dozen volumes or so. | |
