SUMMARY

The discussion focuses on identifying all nonisomorphic abelian groups of order 23 32 5. The key findings indicate that Z23 * Z32 * Z5 is isomorphic to Z360, while Z3 * Z100 is not isomorphic to the original group structure due to differing compositions. The confusion arises from the interpretation of these group structures, particularly in distinguishing between abelian and nonabelian groups.

PREREQUISITES
  • Understanding of group theory concepts, specifically abelian groups.
  • Familiarity with the classification of finite abelian groups.
  • Knowledge of isomorphism in the context of algebraic structures.
  • Basic operations involving direct products of groups.
NEXT STEPS
  • Study the classification theorem for finite abelian groups.
  • Learn about the structure theorem for finitely generated abelian groups.
  • Explore the properties of direct products in group theory.
  • Investigate examples of nonabelian groups and their characteristics.
USEFUL FOR

Mathematics students, particularly those studying abstract algebra, group theorists, and anyone interested in the classification of finite groups.

Homework Statement


- List all nonisomorphic abelian groups of order 2^3 3^2 5


Homework Equations





The Attempt at a Solution


- Z_2^3 * Z_3^2 * Z_5 = (iso) Z_360.
Z_2^3 * Z_3 * Z_3 * Z_5 = (iso) Z_3 * Z_100

I know ,
but why Z_360 , Z_3 * Z_100 are nonisomorphic to 2^3 3^2 5 ?
 
Physics news on Phys.org
Because Z_360 == Z_2^3 * Z_3^2 * Z_5, but Z_3 * Z_100 == Z_2^3 * Z_3 * Z_3 * Z_5.
 
Sorry, I don's understand it..
Z_2^3 * Z_3 * Z_3* Z_5 == Z_8 * Z_9 * Z_5 Is this nonabelian groups of order
2^33^25 ??
