The
dihedral group [D.sub.n] is determined by its endomorphism monoid in the class of all groups.
At
dihedral group of order 8 there is a possibility of 8 groups; we assumed the same from [G.sub.1] to [G.sub.8] and its corresponding ring monomials from [R.sub.1] to [R.sub.8].
Being of immediate urgency, it would be important to analyse diagrams symmetric under the nth
dihedral group (Section 2) that are generated by one massless and one massive propagator per bubble.
Also for the
dihedral groups [I.sub.2] (m) studied in Section 5, the number 1 is [I.sub.2](m)-distinguishing.
Indeed, in the thin building associated with the infinite
dihedral group, no panel admits a parallel residue.
Thus, the m-cover poset yields a Fuss-Catalan generalization of the above mentioned Cambrian lattices, namely a family of lattices parametrized by an integer m, such that the case m = 1 yields the corresponding Cambrian lattice, and the cardinality of these lattices is the generalized Fuss-Catalan number of the
dihedral group and the symmetric group, respectively.

Let G = [D.sub.10] = [C.sub.5] * [C.sub.2], where [D.sub.10] is the
Dihedral group of 10 elements, [C.sub.2] and are cyclic subgroups of orders 2 and 5 respectively, with normal (Frobenius Kernel) and non-normal (Frobenius complement).
In Section 6 we compute the orbicycle index polynomial for the
dihedral groups.
There exist two non-isomorphic groups of order 34: the cyclic group of order 34 and the
dihedral group of order 34.
(6), we can conclude that N([[GAMMA].sub.1](18))/[+ or -][[GAMMA].sub.1](18) = ([5][W.sub.2],[W.sub.9]) is isomorphic to the
dihedral group [D.sub.6].
They are 2-pyramidal under [Z.sub.2] and [Z.sub.4], respectively and their full automorphism groups are both isomorphic to the
dihedral group of order 8.
