Query: Hypersurface exceptional singularities   This paper studies hypersurface exceptional singularities in $\mathbb C^n$
defined by non-degenerate function. For each canonical hypersurface
singularity, there exists a weighted homogeneous singularity such that the
former is exceptional if and only if the latter is exceptional. So we study the
weighted homogeneous case and prove that the number of weights of weighted
homogeneous exceptional singularities are finite. Then we determine all
exceptional singularities of the Brieskorn type of dimension 3.
