Comment (by ncohen):
A couple of remarks:
- Bad indentation in the 'reference' blocks.
- This is ridiculous
{{{
sum(map(lambda i: P[a.index(g**(2*i))], xrange(1, 2*t)))
}}}
Forget these lambda functions and use Python. It will be easier to read,
and less costly in memory/computations. What you want is
`sum(P[a.index(g**(2*i))] for i in range(1,2*t))`.
- You did the right thing when you defined the function `B(m)`. Please do
the same for the lambda function that you use to define `A`.
