Generating sets of finite groups

WebLet G be a finite group. The enhanced power graph Γ G e of G is the graph with vertex set G and two distinct vertices are adjacent if they generate a cyclic subgroup of G. In this article, we calculate the rainbow connection number of Γ G e . WebA generating set is called Nielsen reduced if there is not too much cancellation in products. The paper shows that every finite generating set of a subgroup of a free group is (singularly) Nielsen equivalent to a Nielsen reduced generating set, and that a Nielsen reduced generating set is a free basis for the subgroup, so the subgroup is free.

WebFeb 5, 2024 · There were a few proofs or hints at proofs, including here on MSE and also on MathOverflow, but they were either too advanced, didn't give enough details, assumed theory I can't assume at this point (for example about rings or principle ideal domains), or were extremely complicated (as in 4 pages with 4 lemmas that needed to be proven first ... WebFeb 7, 2014 · Given any two generating subsets of the group that satisfy those defining relations, there is an automorphism that takes one set to the other.

WebAny group that acts on a tree, freely and preserving the orientation, is a free group of countable rank (given by 1 plus the Euler characteristic of the quotient graph). The Cayley graph of a free group of finite rank, with respect to a free generating set, is a tree on which the group acts freely, preserving the orientation. WebCorollary: A finitely generated abelian group is free if and only if it is torsion-free, that is, it contains no element of finite order other than the identity. The number \(r\) is called the rank of \(A\).
