Abstract: For smooth immersions of 2-manifolds into $ {E^M}$, the condition of 0-tightness is equivalent to that of minimal total absolute curvature, but for higher dimensional manifolds these notions are quite different. By a result of Chern and Lashof, a smooth n-sphere embedded in $ {E^M}$ with minimal total absolute curvature must bound a convex $ (n + 1)$-cell in an affine $ (n + 1)$-dimensional subspace, but we show that for any $ n > 2$ and any $ M > n$ there is a 0-tight polyhedral embedding of the n-sphere into $ {E^M}$ with image lying in no hyperplane.
