In "Notes on Finite Group Theory"
by Peter J. Cameron (October 2013),
http://www.maths.qmul.ac.uk/~pjc/notes/gt.pdf,
some parts are particularly related to the mathematics of
the 4×4 square (viewable in various ways as four quartets)—
- Definition 1.3.1, Group actions, and example on partitions of a 4-set, p. 19.
- Exercise 1.1, The group of Fano-plane symmetries, p. 35.
- Exercise 2.17, The group of the empty set and the 15 two-subsets of a six-set, p. 66.
- Section 3.1.2, The holomorph of a group, p. 70.
- Exercise 3.7, The groups A8 and AGL(4,2), p. 78.
Cameron is the author of Parallelisms of Complete Designs ,
a book notable in part for its chapter epigraphs from T.S. Eliot's
Four Quartets . These epigraphs, if not the text proper, seem
appropriate for All Saints' Day.
