Structure of wrap groups of quaternion and octonion fiber bundles
  This article is devoted to the investigation of structure of wrap groups of connected fiber bundles over the fields of real $\bf R$, complex $\bf C$ numbers, the quaternion skew field $\bf H$ and the octonion algebra $\bf O$. Iterated wrap groups are studied as well. Their smashed products are constructed.
