I have a list of positive and negative integers, and I would like to specify specific elements of the list and get all possible ways the list can contain those elements being both positive and negative. For example, if I have the list {2,4,6} and select elements 1 and 3 I would like to get back {2,4,6}, {-2,4,6}, {-2,4,-6}, {-2,4,-6}.
Any help in would be greatly appreciated, even just a line of thought. Results so far have been very poor :S
