SUMMARY

The discussion focuses on finding the 2-Sylow and 3-Sylow subgroups of the symmetric groups ##S_3## and ##S_4##. It is established that the order of ##S_3## is 6, leading to a 2-Sylow subgroup of order 2 and a 3-Sylow subgroup of order 3. For ##S_4##, with an order of 24, the 2-Sylow subgroups can be identified, and the discussion confirms that the permutations ##(1 2), (1 3), (2 3)## serve as generators for the 2-Sylow subgroup of ##S_3##.

PREREQUISITES
  • Understanding of group theory concepts, specifically Sylow theorems
  • Familiarity with symmetric groups, particularly ##S_3## and ##S_4##
  • Basic knowledge of permutation notation and operations
  • Ability to compute group orders and apply the Sylow counting theorem
NEXT STEPS
  • Study the Sylow theorems in detail to understand subgroup structures
  • Explore the properties of symmetric groups, focusing on their subgroup lattices
  • Learn about the application of Sylow subgroups in group classification
  • Investigate the relationship between group actions and permutation representations
USEFUL FOR

Mathematics students, particularly those studying abstract algebra, group theorists, and anyone interested in the structure of symmetric groups and their subgroups.

Homework Statement



Find the three 2-Sylow subgroups of ##S_3## and find a 2-Sylow subgroup and a 3-Sylow subgroup of ##S_4.##

2. The attempt at a solution

I got ##|S_3| = 6 = 2\dot\ 3## and ##|S_4| = 24 = 2^3\dot\ 3.## So ##S_3## has a a Sylow 2 subgroup of order 2 and a Sylow 3 subgroup of order 3. I am asked to find the three 2-Sylow subgroups of ##S_3## so since the 2-Sylow of ##S_3## has order 2 is it just the permutations ##(1 2), (1 3), (2 3)? ##

Those are the generators of the only subgroups of S_3 of order 2, so yes.
