Minimal and random generation of permutation and matrix groups
MetadataShow full item record
We prove explicit bounds on the numbers of elements needed to generate various types of finite permutation groups and finite completely reducible matrix groups, and present examples to show that they are sharp in all cases. The bounds are linear in the degree of the permutation or matrix group in general, and logarithmic when the group is primitive. They can be combined with results of Lubotzky to produce explicit bounds on the number of random elements required to generate these groups with a specified probability. These results have important applications to computational group theory. Our proofs are inductive and largely theoretical, but we use computer calculations to establish the bounds in a number of specific small cases.

Coutts, Hannah Jane (University of St Andrews, 2011-11) - ThesisPart I of this thesis presents methods for finding the primitive permutation groups of degree d, where 2500 ≤ d < 4096, using the O'Nan-Scott Theorem and Aschbacher's theorem. Tables of the groups G are given for each ...
Plötner, Maria; Over, Harriet; Carpenter, Malinda; Tomasello, Michael (2016-03-24) - Journal articleTo date, developmental research on groups has focused mainly on in-group biases and intergroup relations. However, little is known about children’s general understanding of social groups and their perceptions of different ...
Cognition in inter-group relations : the effect of group membership on theory of mind and its precursors McClung, Jennifer (University of St Andrews, 2012) - ThesisSocial categorization based on group membership has a significant and broad influence on behaviour (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987). People perceived as being of the same group, ‘in-group’ members, are ...
