Comment (by ncohen):
Hello again,
I pushed a couple of modifications at `public/19778`. [A typo here/a
comment there], though I also added a couple of checks in a test, and
multiplied by (q-1) instead of using `// (q-1)`, just in case the integer
division may make equal two values which should not be. I also used 'izip'
in a loop somewhere: you are welcome to revert it if you do not like it,
and to change the ticket's status when you are satisfied with the code.
Thanks for this addition! I will not get a look at the ticket above this
one.
Nathann
