## Question

"Taking a collection of sets A whose union is all of [math]\mathbb{Q}[/math] and passing to the limit of the corresponding z-sequences, we obtain an example that is multiplicative everywhere."

Do you mean an *increasing sequence* of sets A, whose union is Q? --SuneJ 10:39, 12 January 2010 (UTC)
