Hi, Sorry I'm not sure where I should post this, so hopefully this forum is ok. Is it possible to have two interpenetrating percolated networks of randomly arrange spheres of the same size? So if I have a 50% concentrationg of sphere A, and 50% of sphere B and arrange them randomly within a lattice, will I have percolating clusters of both? What is the critical density for percolation of either network? I couldn't see the answer online, maybe because I don't really know what to search for but it sounds like the sort of thing that should be known. Thanks. Edit: found it. 0.31 apparently.
