  We prove equality of the vector field (iterated commutator) type and the
regular contact type, which together with the Bloom theorem on equality of the
Levi-form type and the regular contact type provides a complete solution of a
long standing open problem of Bloom in the case of complex dimension three. For
general dimensions, we verify the Bloom conjecture when $s=n-2$, which provides
the first positive result in the pseudoconvexity sensitive case for a real
hypersurface in ${\mathbb{C}}^n$ after his important work in 1981.
