Removing duplicate points in Grasshopper

Hi guys,

I wanted to remove duplicate points from 2 list of points. Do any of you know a way to do this? I have read other forums but it doesn't work and I can't use plugins to do this as I can only use grasshopper as a tool. Can any of you give me a suggestion as how to do this? I tried using the similarity component but it didn't work as its output gives all of the points for some reason. Thank you for your help.

My 1st list:

{5.0, 1.0, 3.0}

{9.0, 5.0, 3.0}

{5.0, 9.0, 3.0}

{1.0, 5.0, 3.0}

{5.0, 5.0, 0.0}

{5.0, 5.0, 6.0}

My 2nd list:

{1.0, 5.0, 3.0}
