Abstract Alg I
1. Can you explain why Z/8Z and the dihedral group D_4 are not isomorphic? 2. Consider the subgroup of S_4 generated by the two permutations (12)(34) and (13)(24). Also consider the subgroup generated by (12) and (34). Are these groups isomorphic? Why or why not? Hint: check out the multiplication table

1. A Cayley diagram and multiplication table for the dihedral group Ds are shown below Section 2 of the class lecture notes describes two algorithms for expressing a group G of order n as a set of permutations in Sn. One algorithm uses the Cayley diagram and the other uses the multiplication table. In this problem, you will explore this a bit further.

11. Let G = Z4 Z4, H = {0,0), (2,0), (0,2), (2,2)). Write the Cayley table for G/H. Is G/H isomorphic to Z4 or Z2 x Z ? Justify your answer. 12. Show that G = {1, 7, 17, 23, 49, 55, 65, 71} is a group under multiplication modulo 96. Then express G as an external and an internal direct product of cyclic groups.

// Use the following
Project: Perfect Square Table
A “Perfect Square Table” is a square of positive
integers such that the
sum of each row, column, and diagonal is the same
constant.
This program reads square tables from files, checks if
they are perfect squares,
and displays messages such as “This is a Perfect
Square Table with a constant of 34!”
or “This is not a Perfect Square Table”.
