We discuss mechanisms for the production of exotic hadrons in heavy-ion collisions at high energy, focusing on the doubly strange /ital H/ dibaryon. In a hadron gas phase, we estimate the /ital H/ formation rate, per central Si+Au collision, to be of order 0.01 for temperatures /ital T/=120--140 MeV, based on a conventional coalescence model. If the quark-gluon plasma phase is excited, we expect an enhancement relative to the rate for a hadron gas. We explore various schemes for detecting the /ital H/ in the high multiplicity background characteristic of heavy-ion collisions. The proposed detection techniques include the measurement of weak decays such as /ital H//r arrow/..sigma../sup /minus//p, the search for nuclear fragments with anomalous charge/mass ratio, and diffractive dissociation processes such as /ital Hp//r arrow/..xi../sup /minus//pp. .AE
