The probability of randomly generating finite abelian groups

Tyler Carrico

Full-text: Open access

Abstract

Extending the work of Deborah L. Massari and Kimberly L. Patti, this paper makes progress toward finding the probability of k elements randomly chosen without repetition generating a finite abelian group, where k is the minimum number of elements required to generate the group. A proof of the formula for finding such probabilities of groups of the form pmpn, where m,n and  p is prime, is given, and the result is extended to groups of the form pn1pnk, where  ni,k and p is prime. Examples demonstrating applications of these formulas are given, and aspects of further generalization to finding the probabilities of randomly generating any finite abelian group are investigated.
