Query: Non-Trivial SU(N) Instantons and Exotic Skyrmions   The classical Yang-Mills equations are solved for arbitrary semi-simple gauge
groups in the Schwinger-Fock gauge. A new class of SU(N) instantons is
presented which are not embeddings of SU(N-1) instantons but have non-trivial
SU(N) color structure and carry winding number $n=N(N^{2}-1)/6$. Explicit
configurations are given for SU(3) and SU(4) gauge groups. By means of the
Atiyah Manton procedure Skyrmion fields are constructed from the SU(N)
instantons. These Skyrmions represent exotic baryon states.
