Query: On the Size of $\exists$-Generalized Concepts   Formal Concept Analysis (FCA) offers several tools for qualitative data
analysis. One possibility is to group objects that share common attributes
together and get a concept lattice that describes the data. Quite often the
size of this concept lattice is very large. Many authors have investigated
methods to reduce the size of this lattice. In \cite{KMBV14} the authors
consider putting together some attributes to reduce the size of the attribute
sets. But this reduction does not always carry over the set of concepts. They
have provided some counter examples where the size of the concept lattice
increases by one after putting two attributes together. Then they asked the
following question: "How many new concepts can be generated by an
$\exists$-generalization on just two attributes?" The present paper provides a
family of contexts for which the size increases on more than one concept after
putting solely two attributes together.
