Abstract We investigate Arhangel'skǐi's problem of whether Lindelof T 2 spaces with points G δ have cardinality ⩽ 2 ℵ 0 . We extend results of Shelah, using supercompact cardinals to exclude cardinalities between ℵ 1 and 2 ℵ 1 . We also obtain several results concerning the possible structure of large Lindelof spaces with points G δ .
