The regular expressions of PSL have the common operators for concatenation ({{mono|;}}), Kleene-closure ({{mono|*}}), and union ({{mono|{{!}}}}), as well as operator for fusion ({{mono|:}}), intersection ({{mono|\&\&}}) and a weaker version ({{mono|\&}}), and many variations for consecutive counting {{mono|[*n]}} and in-consecutive counting e.g. {{mono|[{{=}}n]}} and {{mono|[->n]}}.
