Maximal Subgroups of Infinite Symmetric Groups

Journal of the London Mathematical Society, 1990
It is shown that if G is a permutation group on a countable set X and if G is not highly transitive, then G is contained in some maximal proper subgroup of the full symmetric group on X.

Maximal Subgroups of Infinite Symmetric Groups

Canadian Mathematical Bulletin, 1967
The purpose of this paper is to extend results of Ball [1] concerning maximal subgroups of the group S(X) of all permutations of the infinite set X. The basic idea is to consider S(X) as a group of operators on objects more complicated than X. The objects we consider here are subspaces of the Stone-Čech compactification of the discrete space X and the ...

SYMMETRIC GROUPS AS PRODUCTS OF ABELIAN SUBGROUPS

Bulletin of the London Mathematical Society, 2002
Summary: A proof is given that the full symmetric group over any infinite set is the product of finitely many Abelian subgroups. In fact, 289 subgroups suffice. Sharp bounds are also obtained on the minimal number \(k\), such that the finite symmetric group \(S_n\) is the product of \(k\) Abelian subgroups.

Maximal Abelian Subgroups of the Symmetric Groups

Canadian Journal of Mathematics, 1971
Our aim is to present some global results about the set of maximal abelian subgroups of the symmetric group Sn. We shall show that certain properties are true for “almost all” subgroups of this set in the sense that the proportion of subgroups which have these properties tends to 1 as n → ∞.

Normal subgroups of nonstandard symmetric and alternating groups

Archive for Mathematical Logic, 2007
Let \({\mathcal M}\) be a nonstandard model of Peano arithmetic, with domain \(M\), and \(n\in M\) be a nonstandard natural number. Denote by \(S_n\) and \(A_n\) the symmetric and the alternating group of permutations of the internal set \(\{0,1,\dots,n-1\}\), respectively. By the transfer principle, \(S_n\) and \(A_n\) have all the usual properties of

SOME MAXIMAL SUBGROUPS OF INFINITE SYMMETRIC GROUPS

The Quarterly Journal of Mathematics, 1996
Several classes of maximal subgroups of symmetric groups \(S=\text{Sym}(\Omega)\) where \(|\Omega|=\kappa\) is infinite are investigated. A collection \(\mathcal I\) of subsets of \(\Omega\) is called an ideal on \(\Omega\) if \(\emptyset\in{\mathcal I}\), \(\Omega\notin{\mathcal I}\), and \(\mathcal I\) is closed under taking subsets and finite unions.

ON CERTAIN MAXIMAL SUBGROUPS OF SYMMETRIC AND ALTERNATING GROUPS

Mathematics of the USSR-Sbornik, 1972
This paper deals with the problem of describing the maximal subgroups of symmetric and alternating groups. Certain primitive groups which are not multiply transitive are considered, and it is shown that among these there are infinite series of groups which are maximal in symmetric and alternating groups. Figures: 3. Bibliography: 15 items.

Derangements in Sylow subgroups of symmetric groups

Ars Comb., 1997
Let \(p\) be a prime, and \(H_n\) a Sylow \(p\)-subgroup in \(S_n\). The authors find a recursive formula that expresses the number \(h_n\) of derangements (i.e.~permutations with no point fixed) in \(H_n\). If \(f_n=h_n/|H_n|\) and \(g_n=(f_1+\cdots+f_n)/n\), then, as they show, the sequence \(g_n\) converges to \(0\), while the set \(\{f_n;\;n\geq 1\}
