Query: Appendix to "Real second-order freeness and the asymptotic real
  second-order freeness of several real matrix models": Examples and Diagrams   We present examples and diagrams illustrating the proofs appearing in "Real
second-order freeness and the asymptotic real second-order freeness of several
real matrix models", to which this paper is meant to be an appendix. We show
how matrix calculations may be represented by topological surface gluings,
which may in turn be represented as permutations.
