We present here a very deep spectroscopic survey of galaxies on the line of sight to Coma, based on redshifts obtained with VLT/VIMOS for 715 galaxies in the unprecedented magnitude range 21<R<23 (absolute magnitude -14 to -12). We confirm the substructures previously identified in Coma by Adami et al. (2005a), and identify three new ones. We detect many groups behind Coma: a large structure at z~0.5, the SDSS Great Wall, and a large and ve","authors_text":"A. Biviano, A. Mazure, C. Adami, F. Durret, F. Lamareille, M.P. Ulmer, O.
