[Category:Model](/Category:Model"wikilink")*Z*<sub>*N*</sub> and *U*(1) global symmetries can be defined. For this purpose, a new array <span>Global</span> has been introduced:
Global[[/1|1]] = {Z[2], RParity};
Global[[/2|2]] = {U[1], PecceiQuinn};
First, the kind of the symmetry is defined and afterwards a name is given to the symmetry. In principle, up to 99 different global symmetries can be defined for one model. Note, *Z*<sub>*N*</sub> symmetries are always understood as multiplicative symmetries. The second entry gives a name to the symmetry.
