Finding Probability of Generating Symmetric Group Sn

Click For Summary
SUMMARY

The discussion focuses on the mathematical problem of determining the probability that two randomly chosen elements from the symmetric group Sn generate the entire group Sn. The elements in question are defined as random variables X and Y, which are independent and uniformly distributed over Sn. The goal is to derive a formula for the probability P(=Sn), where represents the subgroup generated by X and Y.

PREREQUISITES
  • Understanding of symmetric groups, specifically Sn.
  • Knowledge of random variables and their properties.
  • Familiarity with group theory concepts, particularly subgroup generation.
  • Basic probability theory, including the concept of independent events.
NEXT STEPS
  • Research the properties of symmetric groups and their applications in group theory.
  • Study the concept of subgroup generation in finite groups.
  • Explore probability theory related to random variables and their distributions.
  • Investigate existing literature on the probability of generating groups, particularly in the context of symmetric groups.
USEFUL FOR

Mathematicians, students of abstract algebra, and anyone interested in group theory and probability, particularly those exploring unsolved problems in mathematics.

This is from Wikipedia's "unsolved problems in math" section:

Finding a formula for the probability that two elements chosen at random generate the symmetric group Sn

Can someone explain that to me? I know what Sn is. What are these two "elements"?

I'm not sure what's unclear. As the article said, the "elements" are random variables -- presumably independent and uniformly distributed.

If X and Y are random variables with domain Sn, then <X,Y> is a random variable whose domain is the set of all subgroups of Sn. The question is to find a formula for P(<X,Y>=Sn).
