# Definition talk:Indexing Set/Function

This is indexed family—maybe it should be pointed out here or there that there also exist generic families, especially that Definition:Family redirect here… (They are images of $x$ used in definitions; this way "family" is just different name for "set", e.g. "family of sets" or "family of lines" instead of "set of sets" or "set of lines" etc.) joel talk 17:37, 29 December 2012 (UTC)
