Query: A small and non-simple geometric transition   Following notation introduced in the recent paper \cite{Rdef}, this paper is
aimed to present in detail an example of a "small" geometric transition which
is not a "simple" one i.e. a deformation of a conifold transition. This is
realized by means of a detailed analysis of the Kuranishi space of a Namikawa
cuspidal fiber product, which in particular improves the conclusion of
Y.~Namikawa in Remark 2.8 and Example 1.11 of \cite{N}. The physical interest
of this example is presenting a geometric transition which can't be immediately
explained as a massive black hole condensation to a massless one, as described
by A.~Strominger \cite{Strominger95}.
