so knots only exist when there are exactly 3 dimensions? That's interesting.

- mathgenius 5y agoThe fourth dimension is enough to untangle a knot made out of a one dimensional space (a loop of string). But you can make two dimensional knots in four dimensional space: this is a surface that is knotted with itself in four dimensions. And probably the pattern extends to higher dimensions.
