Abstract

In this article, we find the cyclic decomposition of the finite abelian factor group 1.PNG where 2.PNG and m is an even number and 3.PNG is the quaternion group of order 4m.

(The group of all Z-valued generalized characters of G over the group of induced unit characters from all cyclic subgroups of G).

We find that the cyclic decomposition 4.PNG depends on the elementary divisor of m. We have found that if 5.PNG are distinct primes, then:

6.PNG

Moreover, we have also found the general form of Artin characters table 7.PNG when m is an even number.
