SUMMARY

The notation S_4(2) refers to a specific group related to the symmetric group S_4, which encompasses all permutations of four objects. In this context, S_4(2) denotes a subgroup of S_4 that is associated with particular properties or structures within group theory. The discussion clarifies that S_4(2) and S_4(3) are not merely sequences or partial sums but represent distinct groups within the framework of permutation groups.

PREREQUISITES
  • Understanding of group theory concepts
  • Familiarity with symmetric groups, specifically S_n
  • Knowledge of permutation notation and operations
  • Basic comprehension of subgroup relationships
NEXT STEPS
  • Research the properties of symmetric groups, particularly S_4
  • Explore subgroup structures within group theory
  • Learn about the significance of notation in group classifications
  • Investigate examples of S_n groups and their applications
USEFUL FOR

Mathematicians, students of abstract algebra, and anyone interested in the study of group theory and permutations.

Hi...

Could someone tell me what is meant by S_4 (2),S_4(3) etc? These are names of some groups...

I believe it means a sequence at a certain number, partial sum.
 
No...not that..

This is in another context...these are names of some groups...It must mean that the group is related to S_4, the group of all permutations of 4 objects...
But I do not know what the relation is..
 

Thread 'Confusion about the Moyal-Weyl twist'

I am studying the mathematical formalism behind non-commutative geometry approach to quantum gravity. I was reading about Hopf algebras and their Drinfeld twist with a specific example of the Moyal-Weyl twist defined as F=exp(-iλ/2θ^(μν)∂_μ⊗∂_ν) where λ is a constant parametar and θ antisymmetric constant tensor. {∂_μ} is the basis of the tangent vector space over the underlying spacetime Now, from my understanding the enveloping algebra which appears in the definition of the Hopf algebra...
