Word for 4D space. The previous ones are realm, plane, line and point
Random mathematician who saw the V&D wiki: so you see the Klein bottle won't intersect itself if you put it in a flune instead of a realm, but since it has a surface you can't fill it anymore because it doesn't enclose any bulk
Person: what the heck is a flune?
Mathematician:
