Talk:Cardinality of Set of All Mappings

GFauxPas: Where have you seen this result quoted for infinite sets? --prime mover 15:13, 18 January 2012 (EST)


 * Hmm... You will typically need PCC (the Principle of Cardinal Comparability, equivalent to AC, saying that for sets $X,Y$, $|X|\le|Y|$ or vice versa) to show things like that. But assuming PCC, the result 'does' hold for infinite sets as well. --Lord_Farin 15:17, 18 January 2012 (EST)
