#F  GeneratorsOfNumericalSemigroupNC(S)
##
##  Returns a set of generators of the numerical
##  semigroup S.

#####From version 0.980 is just a synonym of the check version of the function

#F  ReducedSetOfGeneratorsOfNumericalSemigroup(arg)
####From version 0.980 is a synonym of MinimalGenerating...
##
##  Returns a set with possibly fewer generators than those recorded in <C>S!.generators</C>. It changes <C>S!.generators</C> to the set returned.
##The function has 1 to 3 arguments. One of them a numerical semigroup. Then an argument is a boolean (<E>true</E> means that all the elements not belonging to the Apery set with respect to the multiplicity are removed; the default is "false") and another argument is a positive integer <M>n</M> (meaning that generators that can be written as the sum of <n> or less generators are removed; the default is "2"). The boolean or the integer may not be present. If a minimal generating set for <M>S</M> is known or no generating set is known, then the minimal generating system is returned.

#F  FortenTruncatedNCForNumericalSemigroups(l)
##
##  l contains the list of coefficients of a
##  single linear equation. FortenTruncatedNCForNumericalSemigroups
##  gives a minimal generator
##  of the affine semigroup of nonnegative solutions of this equation
##  with the first coordinate equal to one.
##
##  Used for computing minimal presentations.

#F  IsConnectedGraphNCForNumericalSemigroups(l)
##
## This function returns true if the graph is connected an false otherwise
##
## It is part of the NumericalSGPS package just to avoid the need of using
## other graph packages only to this effect. It is used in
## CatenaryDegreeOfElementNS
