Dimensions of Spaces

BrandtModuleDimension(D, N) : RngIntElt, RngIntElt -> RngIntElt
The dimension of the Brandt module of level (D, N), computed by means of standard formulas.

Example ModBrdt_ModBrdt:Dimension (H143E6)

In the following example we demonstrate the computation of the dimensions of the Brandt modules for the sequence of Eichler orders of index 3i in a maximal order in the quaternion algebra of discriminant 2.3 .7.
> D := 2*5*7;
> for i in [0..10] do
>     BrandtModuleDimension(D,3^i);
> end for;
