From CoCoAWiki

## BB.Box

Computes a box order ideal.

### Syntax

BB.Box(D:LIST):LIST

### Description

Computes the box order ideal of type `D=[D_1,..,D_N]`. The input is a list of integers `D` of length ApCoCoA:NumIndets(). The output is a list of terms sorted in ascending order with respect to the current term ordering.

@param

*D*List of integer values representing an exponent vector of a term. The order ideal spanned by the term represented by this exponent vector will be computed.@return A list of terms of the order ideal spanned by the term represented by the exponent vector

`D`, sorted in ascending order w.r.t. the current term ordering.

#### Example

Use QQ[x,y,z]; BB.Box([2,1,1]); [1, z, y, x, yz, xz, xy, x^2, xyz, x^2z, x^2y, x^2yz] -------------------------------
