The hydroxide ligands in the plane are either doubly bridging or triply bridging. Some oxide ligands are terminal, some doubly bridging, and a few are triply bridging ligands. Doubly weak verbs have two "weak" radicals; a few verbs are also triply weak. The detection of triply deuterated ammonia was considered a surprise as deuterium is relatively scarce. HeY is predicted to be the lightest stable diatomic triply charged ion. The Schwarz surfaces have topological genus 3, the minimal genus of triply periodic minimal surfaces. The compound adopts a cubane-like structure with four triply bridging iodide ligands. Each Aerial Platform is equipped with a triply redundant avionics system. It is the only triply landlocked U.S. state. The sulfur end of the SCN- ligand is triply bridging. Smith adapted the triply convergent strategy of the Schreiber synthesis. Nebraska is the only triply landlocked state. An example of a triply lensed quasar is PG1115+08. In differential geometry, the lidinoid is a triply periodic minimal surface. Then there would be the aforementioned "triply clean meat" rule.
