This is definitely not a bug. The definition of the _add_ method
absolutely demands that both inputs have exactly the same parent. In
the above instance, the left hand input (=1) has parent ZZ, and the
right hand input (=SR(2)) has parent the symbolic ring.
Yeah, I know that-- it's the
Hi thanks for your answers,
I used _inverter_, _mul_, _add_ etc, because apparently
the implementation work fine but only apparently,
i think that the essencial problem is with _invert_ method,
but now I used inverse_mod , but I dont

always give empty vector, here sigma.roots() should nonzero vector

Hi everybody,
I am implement Patterson Algorithm for Goppa code,
I am copying lines from paper How SAGE helps to implement Goppa
Codes and McEliece PKCSs [attach], and my test is a random vector .
the error are in Line 77,
I expect get roots from \sigma (locator polynomial), but

I don't think you should need to call _add_, but this looks like a bug to me:
