I have been computing modular symbols for distinct curves on the Cremona
data base.
But, in a few curves, I recived a WARNING messages like this:
Warning : Could not normalize the modular symbols, maybe all further
results will be multiplied by -1, 2 or -2.
Why sage does not give the exa

file signals.so has differences between SageMath 7.3 and SageMath 7.4.*
