From ApCoCoAWiki

## BBF.RetrieveUGenerators

Retrieve generators of order ideal U.

### Syntax

BBF.RetrieveUGenerators():LIST

### Description

*Please note:* The function(s) explained on this page is/are using the *ApCoCoABBFServer*. You will have to start the ApCoCoABBFServer in order to use it/them.

Retrieve the set of generators of the order ideal U representing the computing universe from ApCoCoABBFServer.

@return List of generators of order ideal U.

#### Example

Use ZZ/(32003)[x, y, z],DegLex; I:=Ideal(-4*x^2 + 1, -4*y^2 - 1, 5*z^2); BBF.Init(I); BBF.Finish(); -- After computation has finished: BBF.RetrieveUGenerators(); Output: [xyz^2, xy^2z, x^2yz]
