### Converting Graphics geometry to a Graph

I need a representation of a 3D Sierpinski Gasket in a form of a graph to perform some simulations on. The 2D version is included in Graphdata[] but the 3D one is nowhere to be found, so I was ...

### Remove inner points from collinear List

Imagine a List of Points that is collinear: {{-1,-1},{1,1},{0,0},{-2,-2},{1,1}} How can I at first check, if such a List is collinear and if so, reduce it to ...
