The PariGP data on the page
https://www.lmfdb.org/ModularForm/GL2/Q/holomorphic/80/5/h/b/for Newform orbit 80.5.h.b, namely,
[N,k,chi] = [80,5,Mod(79,80)]
is not correct.
It is the same as the data for Newform orbit 80.5.h.a
[N,k,chi] = [80,5,Mod(79,80)]
https://www.lmfdb.org/ModularForm/GL2/Q/holomorphic/80/5/h/a/This data does appear to be correct for Newform orbit 80.5.h.a, when I use it in PariGP.
It would be great if someone could fix the PariGP data for Newform orbit 80.5.h.b, as I would like to work with it in PariGP.
The data for Magma and SageMath may be wrong also.
