[edit] Notation

Notation question: the author of this page uses the following notation for equinumerous sets: A \approx B.\, Is this more correct than: A \sim B.\, which is what is used in Apostal, "Mathematical Analysis". Lemasterda 16:49, 14 October 2007 (UTC)

I have seen the former used more often than the latter for this meaning. JRSpriggs 17:02, 14 October 2007 (UTC)
