Attractor Point selection True+False

Hi,

Struggling with this issue!

-I have a curve which has been divided into a number of points.

-From the points i have randomly selected 3 points to act as attractor points along the curve.

-Using the closest points function i can select a the points closest to the attractor points. All pretty simple!

- However i also want to be able to select the remaining points! 

-I tried another way which analyses the distance of the 3 attractor points separately, using the evaluate function leaving me three lists of true or false lists.

What is the best way to select the remaining points?   

Could i use the evaluate function to say analyse two lists and replace any false items with true. this would then be repeated again leaving you with a list you could use to dispatch and separate the points?

E.g If List A = True then replace item in List B

Thanks
