There are all sorts of SETS of uncountably many nested intervals bounded

by irrationals, but no SEQUENCES of them that are uncountable.

If x is any positive irrational, then [-x,x] is an interval bounded by

irrationals.

And { [-x,x] : x is a positive irrational} is a set of uncountably many

nested intervals bounded by irrationals.

But is not a sequence at all.

Get your head straight, Ross!
