One goal of binary heavy-ion collisions is to study strongly interacting matter under extreme conditions e.g. at a high baryon density. Nevertheless, an even higher density can be accomplished by colliding three nuclei instead of two in a Triple Nuclear Collision (TNC). In this work, the process of simulating a TNC with the use of the hadronic transport approach SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) is presented. Furthermore, the observables for particle production of central Pb+Pb+Pb TNCs at energies between 3 GeV and 20 GeV are examined. Simultaneously, these findings are compared with those of binary Pb+Pb collisions with the same respective energy and centrality. Finally, it is shown that a TNC leads to a higher baryon and energy density than in binary collisions, thus exposing a promising method to better understand QCD matter.
