# Moriyama-Takeuchi example of a 2-dim simplicial complex.

# taken from:
# Sonoko Moriyama, "Extendable shellability in dimension two",
# Bachelor's thesis, University of Tokyo, 2000.
# and
# Sonoko Moriyama and Fumihiko Takeuchi, "Incremental construction
# properties in dimension two --- shellability, extendable shellability
# and vertex decomposability", preprint.

# Remark: This is the same as the example by A.Bjorner:
# Andreas Bjorner, "The homology and shellability of matroids and
# geometric lattices", in Matroid Applications, N.White ed.,
# Cambridge Univ.Press, 1992, 226-283. (Exercise 7.37)
