Note �1��2 implies nps � T or �1 and �2 are in two separate components of a PN that is not strongly connected. Also, in any synthesized PN using the TT and PP rules, �1 cannot be both concurrent and exclusive to �2 using the above definition. This is, however, not true for PNs that cannot be synthesized using the TT and PP rules. The above definition of sequential, earlier, and later seem to be also marking related. However, in the synthesized net, any cycle contains at most a place marked with tokens; thus the marked place can be considered a structure. In Figure 8.3, the new PSP � is and .
