چکیده
We will present that the forbidden minors for 3-realizable graph are K5 and the octahedron. You can directly go to Theorem 13 and if necessary refer to the definitions, lemmas and theorems before it. Definition 1 A graph G is d-realizable if, given any realization p1, · · · , pn of the graph in some finite dimensional Euclidean space, there exists a realization q1, · · · , qn in E with the same edge lengths: |pi − pj| = |qi − qj | for all {i, j} ∈ E(G).

We describe further observations of QSO J0906+6930, a z=5.48 blazar likely to be detected in γ-rays. New radio and X-ray data place significant constraints on any kpc-scale extension of the VLBA-detected jet. Improved optical spectroscopy detects absorption from an intervening galaxy at z=1.849 and raise the possibility that this distant, bright source is lensed. We combine the new data into an...
