On repeating links in the "see also" section[edit]

  • JA: Not that big of a deal, but it can be very useful to the reader, both on first and subsequent readings of an article, to have a syllabus of related topics collected in one place. For instance, I think of the times I myself spend looking for a topic I know I saw in some topical connection but can't rememeber where and it's too much of a hassle searching through multiple texts. No trees were harmed in the making of these compendia. Jon Awbrey 04:15, 12 March 2006 (UTC)

Balking at "equivalence" with XOR[edit]

I've just changed the first paragraph, which did call symmetric difference the "set-theoretic equivalent" of exclusive disjunction. For me, that's too much abuse of terminology (viz. equivalent), especially in an article on a mathematical topic. So I've merely replaced equivalent with kin. My replacement is no less vague, but at least its imprecision is more above board.—PaulTanenbaum (talk) 13:03, 28 January 2008 (UTC)


Does anyone have references to where to find this in the (printed) literature ? Who first introduced the symmetric difference (pseudo)metric? —Preceding unsigned comment added by (talk) 12:08, 21 May 2008 (UTC)

Symmetric difference symbol, A\,\Delta\,B or A\ominus B?[edit]

Does anyone know which of the two symbols is more commonly used? – Fuzzy – 13:09, 17 August 2011 (UTC)
