Hey SAGE-Community,
I am new to SAGE and looking for some help for a small university project. Given 𝒪K as the ring of integers to K=ℚ(√5). Given also a totally negative number d ∈ 𝒪K2. How can I calculate the largest integral ideal f in K whose square divides d such that d is a square modulo 4 f?
Thanks a lot in advance!
