Arities of Permutation Groups: Wreath Pr
✍ Gregory L. Cherlin; Gary A. Martin; Daniel H. Saracino πŸ“‚ Article πŸ“… 1996 πŸ› Elsevier Science 🌐 English βš– 1023 KB

We introduce an invariant of finite permutation groups called the arity which is well known to model theorists but has not been examined from an algebraic point of view. There are few cases in which this invariant is known explicitly. We analyze the behavior of this invariant in power representation

Permutation groups on unordered sets II;
✍ Johannes Siemons πŸ“‚ Article πŸ“… 1993 πŸ› Elsevier Science 🌐 English βš– 289 KB

We show that every group is the full automorphism group of an unordered k-relation for given k 2 2 on some suitable set. We are also concerned with the cardinality of a minimal representation with this property as a function of k.

G-Loops and Permutation Groups
✍ Kenneth Kunen πŸ“‚ Article πŸ“… 1999 πŸ› Elsevier Science 🌐 English βš– 131 KB

A G-loop is a loop which is isomorphic to all its loop isotopes. We apply some theorems about permutation groups to get information about G-loops. In particular, we study G-loops of order pq, where p < q are primes and p q -1 . In the case p = 3, the only G-loop of order 3q is the group of order 3q.

Regular orbits of permutation groups on
✍ Peter J Cameron πŸ“‚ Article πŸ“… 1986 πŸ› Elsevier Science 🌐 English βš– 139 KB

If a sequence of transitive permutation groups G of degree n have orders which are not too large (log IGI--o(n~) suttices), then the number of orbits on the power set is asymptotically 2n/]GI, and almost all of these orbits are regular. This conclusion holds in particular for primitive groups.
