DESCRIPTION:Thompson’s group V is probably one of the best kno
wn example of a finitely presented simple group.
The presentation originally given by Thompson in h
is notes appears to have remained the best in term
s of fewest generators and relations for decades.
In this talk\, I will give a number of different
collections of generators\, including a new smalle
r presentation\, for V and comment on generating s
ets for its relatives nV. These will illustrate h
ow Thompson’s group V can be viewed as an infinite
analogue of the finite alternating and symmetric
groups. This is ongoing joint work with Collin Bl
eak.\n
