## BB.Box

Compute 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 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, x] -------------------------------
