BrandtModuleDimension(D, N): RngIntElt, RngIntElt -> RngIntElt#

The dimension of the Brandt module of level \((D,N)\), computed by means of standard formulas.

Example: Mod Brdt:Dimension (ex-4ee604)#

In the following example we demonstrate the computation of the dimensions of the Brandt modules for the sequence of Eichler orders of index \(3^i\) in a maximal order in the quaternion algebra of discriminant \(2\cdot 3 \cdot 7\).

> D := 2*5*7;
> for i in [0..10] do
>     BrandtModuleDimension(D,3^i);
> end for;
