Hi Sebastian,
>From the error message you get when you enter an non-existing method
(e.g., Method->"EducatedGuess") it appears that the only other method
apart from Arnoldi is Automatic.
WRT other options:
In[3]:= Options[Eigenvalues]
Out[3]= {Cubics -> False, Method -> Automatic, Quartics -> False}
gives you the default options.
Cheers -- Sjoerd
