The invariants [a1, a2, a3, a4, a6] of the given genus one model
which must have degree 2, 3, or 4.
The formulae in the degree 3 case come from [ARVT05].
The invariants [b2, b4, b6, b8] of the given genus one model
which must have degree 2, 3, or 4. These are computed from the
aInvariants in the standard way (as for elliptic curves).
The invariants [c4, c6] of the given genus one model.
For n=2, 3, or 4 these are the classical invariants, as can be found in
[AKM+01].
For n=5 the algorithm is described in [Fis08].
The invariants c4, c6 and Δ(the discriminant)
of the given genus one model.
The discriminant Δof the given genus one model.
The SL4-invariants of a genus one model of degree 4.
