\item \TODO \item If the function generating the isomorphisms keeps the same $k=36$
first vertices, the security degrades considerably. Under normal
circumstances, the number of possible isomorphisms is $1107!$. If the
first $36$ vertices are always kept the same, the domain shrinks to
$(1107-36)!=1071!$. While the difference might not seem to be practically
relevant, the security degrades factorially with every further reduction
in graph size.
