Query: Irreducibility and Smoothness of the moduli space of mathematical
  5--instantons over ${\mathbb P}_3$   We prove that the space of mathematical instantons with second Chern class 5
over ${\mathbb P}_3$ is smooth and irreducible. Unified and simple proofs for
the same statements in case of second Chern class $\leq 4$ are contained.
