# Embedding of punctured torus with euclidean metric

A flat two-torus, $T^2$ that is the torus with Euclidean metric needs to at least be embedded in $\mathbb{R}^4$. If we puncture the torus and leave the Euclidean metric on it as inherited (ignoring the issues of completeness), what ambient space could you embed the punctured torus with Euclidean metric?

It is a bit strange to call the flat metric on the torus the Euclidean metric... –  Mariano Suárez-Alvarez Feb 14 '11 at 6:01
Thinking of $T^2$ as $\mathbb R^2/\mathbb Z^2$, the term Euclidean metric makes some sense. :) –  Grumpy Parsnip Feb 14 '11 at 11:23
