1 Introduction
See general introduction on embeddings, notation and conventions in [Skopenkov2016c, 1, 2].
2 Examples
Analogously to the Haefliger trefoil knot for one constructs a smooth embedding . For even this embedding is a generator of ; it is not smoothly isotopic to the standard embedding, but is piecewise smoothly isotopic to it [Haefliger1962]. It would be interesting to know if for odd this embedding is a generator of . The last phrase of [Haefliger1962t] suggests that this is true for .
3 Classification
For some information see [Skopenkov2006, 3.3].
