# Not that triple product

Geometry Level 2

We call the regular circle $$S^{1}$$, and the regular sphere $$S^{2}$$. It is known the torus is the product of two circles $$S^{1} \times S^{1} \neq S^{2}$$, and it is embedded in three dimensions to avoid self-intersection.

What is the minimum number of dimensions $$S^{1} \times S^{1} \times S^{1}$$ must be embedded in to prevent self-intersection?
