The Four-Gated Song

In the spirit of Beckett:

"Bobbies on bicycles two by two…" — Roger Miller, 1965

The Literary Field

A mathematics weblog in Australia today—

Clearly, the full symmetric group contains elements
with no regular cycles, but what about other groups?  
Siemons and Zalesskii showed that for any group 
G 
between PSL(n,q) and PGL(n,q) other than for
(n,q)=(2,2) or (2,3), then in any action of 
G, every
element of 
 has a  regular cycle, except G=PSL(4,2)
acting on  8 points.  The exceptions are due to
isomorphisms with the symmetric or alternating groups.

See the Klein correspondence  at SymOmega today and in this journal.

"The casual passerby may wonder about the name SymOmega.
This comes from the notation Sym(Ω) referring to the symmetric group
of all permutations of a set Ω, which is something all of us have
both written and read many times over."
