As of 1 Jan 2024: Uue–Uoq (E119–E184) are listed here by systematic name. That is 66 articles, of which 6 are articles, and 60 are redirects. E172 is predicted to be the end of period 8 ("noble gas", though it may well be a [not necessarily noble] solid or liquid); in which case E173 would mark the start of period 9. Articles or redirects for E185 and higher (presumably in period 9 or beyond) are not present as there are currently no known detailed predictions that high.
When an element is discovered (synthesized), the element will be removed from this category. (That's when period 8 is not the same as "theoretical extension" anymore.)
