Hi,
i just started learning about petri nets. To understand the petri nets for modelling, i wanted to construct a petri net graph with say n=4. I read about tower of hanoi problem on wikipedia, but i dont get how i should model this system with L type petri net extensions. can anybody tell me how i should work on this system?

Towers of Hanoi problem:(from wikipedia) link below:
