•The Gemini Partnership The Gemini Partnership is capable of organizing is capable of organizing itself to produce highly itself to produce highly competitive, state-of-competitive, state-of-the-art facilitiesthe-art facilities
•““The Gemini whole” The Gemini whole” can can be greaterbe greater than the sum than the sum of the partsof the parts
