Hello math folks
I need your help to help me solve a math trick, any advice is very appreciated

I have these numbers: 4 3 2 1.5 1 0.75 0.5 0.25
I need to create a coll that contains ALL the permutations of these numbers which the sum is always equal to 4
any idea for a quick patch or suggestion?

many thanks
