We report on the latest results for charged and neutral strangelets for Experiment 864. Approximately, 30×10<sup>9</sup> 10% most central collisions were sampled and no strangelets with A<100 and lifetimes greater than 50 ns were observed. To understand the coalescence mechanism for strangeness better, light hypernuclei production has been studied. In E864 we looked for <sup> 4</sup><sub>Λ</sub>H and <sup>3</sup><sub>Λ</sub>H that may be formed in high-energy, heavy-ion collisions through coalescence of nuclear fragments and hyperons and can be detected through their mesonic decay products (<sup>4</sup>He, π<sup>-</sup>) and (<sup>3</sup>He, π<sup>-</sup>). The preliminary results from 13.3×10<sup>9</sup> 10% most central Au-Pt collisions at 11.5 A GeV c<sup>-1</sup> are presented.
