Can the complement of the Petersen graph -when seen as a simplicial complex- be embedded in Euclidean 3-space?

The complement of the Petersen graph is the intersection graph of the 2-point subsets of {1,2,3,4,5}. Explicitly, its vertices are sets of type {i,j} with i != j among 1..5, and two vertices form...
