torAlgDataList(Ideal,List) -- list invariants of a local ring

Synopsis

Description

Extracts data from the hash table returned by torAlgData.

i1 : Q = QQ[x,y,z];
i2 : I = ideal(x*y,y*z,x^3,x^2*z,x*z^2-y^3,z^3);

o2 : Ideal of Q
i3 : torAlgDataList( I, {m, n, Class, p, q, r, PoincareSeries, BassSeries} )
