List combination of items in new isolated list

Hi everyone,

is there any way to find the following:

So, I have a list of n elements which I would split into a list of lets say 6 elements which I would use as an input in Galapagos. Is there a way to go through the list with all the possible combinations of the 30 numbers so I can find the optimal combination of the isolated 6 numbers for my fitness function? Would that too long if my list contains 100 items (100!/(6!*94!)?). Is there any faster way to compute?

I tried jitter than adding the seed slider as the genome, however this does not guarantee that I will find the optimal combination because I cannot control the output of the jitter function. I would need an input I can optimize when generating.
