Comment (by ncohen):
About this part of the code
{{{
+ try:
+ return DuadicCodeEvenPair(F,Q,N)
+ except TypeError:
+ raise TypeError("No quadratic residue code exists for these
parameters.")
}}}
Is there any reason why your replaced the {{{if
not(is_a_splitting(Q,N,n))}}} by this try/catch ? What worries me is that
it could catch `TypeErrors` raised in `DuadicCodeEvenPair` that are real
bugs and not created by this {{{if not(is_a_splitting(Q,N,n))}}}.
