Q. You have asked about recursively denumerable sets on the SeT page. I am not sure if you are questioning:

• 1). the existence of such a sets.
• 2). whether such sets are well-defined

*AND MORE IMPORTANT

• 1). If you are tryimg to illicit more content, please feel free to add content to the page.
• 2). If you are referring to the paradoxes resulting from looking at sets like X = {x: x is a set}, a more limited problem, Russell's Paradox is on the SetTheory page.

In conclusion, perhaps an example of such a set would help. RoseParks
