Hi all~!

I have data set which consist of 3 dimentional position of galaxies.
BUT, there are some galaxies that its position is exactly same.

I want to find each group which have same position as soon as possible.

The data have total ten million galaxies.
(x,y,z: 3d position arrays)

Can anyone help me to find the fastest way to do that in IDL?

Thanks ^^
May you be happy.
