How can I compute the
length of an element
of a group, where by
"length" I mean the minimum
number of generators
needed to write the element,
assuming that I've fixed
a generating set for the group.
In particular, I need to do
this for the symmetric group
using generating set
(1,2), (2,3), (3,4), ... (n-1,n) 

Thanks a lot,
