Infinitely large sequences

The sentence "In the class of divergent sequences in a normed space one can find infinitely large sequences ..." is obscure. Presumably it is intended to mean that divergent sequences in a normed space include as a subclass those sequences for which the norms tend to infinity, but this is not of course the only way that a sequence can diverge and it's not clear why this particular case is singled out for attention, especially since the wording might give the casual reader the impression that this is the only form of divergence.

Looking at the Russian version I see that you are right: not "one can find" but "one singles out". Boris Tsirelson (talk) 22:11, 17 December 2016 (CET)
