The result of is finite volume, but has no boundary. (Just like the surface of a sphere has no bounding edge, but is of finite area, but up one dimension.)
Here's a link to an article in the Notices of the American Mathematical Society with more details.
Just now saw your comment. Somehow missed it earlier. Thanks for the additional information and link!
David, thanks, bookmarked for later.
Cheers!
