Construct the partial order table of unique relations of the semigroup, or else of the concepts produced by Galois derivations.

1 | ```
partial.order(x, type = c("strings", "galois", "pi.rels"), lbs, sel, po.incl)
``` |

`x` |
an object of a ' |

`type` |
whether the object corresponds to string relations, Galois derivations, or |

`lbs` |
(optional) the labels of the unique relations |

`sel` |
(optional) selected elements in ‘x’ for the partial order |

`po.incl` |
(optional, works only with type |

To get the partial order of an entire semigroup, both generators and compound relations must be considered. This information and the labels of the unique relations are given by the `strings`

function. cf. `semigroup`

to see how the `x`

should be specified properly.

Galois derivations are now possible to be partially ordered as well, and this option is based on the output given by the `galois`

function.

An object of '`Partial.Order`

' class with the partial order table in a matrix form.
