[edit] product or ultraproduct

The notation used in the equation [a^{1}], \ldots, [a^{n}] \in \prod M_{i} bothers me. The square brackets suggest we're considering equivalence classes, that is, elements of the ultraproduct, but the text claims that they're elements of the product. I feel like probably [a^{1}], \ldots, [a^{n}] \in M or [a^{1}], \ldots, [a^{n}] \in \prod M_{i}/U was meant instead. Can you verify? -lethe talk + 16:54, 11 April 2006 (UTC)

Good catch. I fixed it. --Trovatore 17:26, 11 April 2006 (UTC)
