Abstract
The stability of tripositronium, a system consisting of three electrons and three positrons, has been investigated
systematically by varying the repulsion strength between like-charged particles. The possibility of the existence
of a Ps3 bound state that is stable against dissociation appears utterly unlikely based on the results of variational
calculations employing all-particle explicitly correlated Gaussian basis functions
