. The infinite dihedral group D[infinity] is a subgroup of permutations of the integers generated by f(n) = −n and g(n) = 1 − n, which reflect the integer number line over the point 0 and 1/2 respectively. (a) Give a presentation of D[infinity]. (b) Demonstrate a surjective homomorphism to each finite dihedral group ϕ : D[infinity] → Dn for n ≥ 3.
