   Abstract:
   By using totally isotropic subspaces in an orthogonal space Ω⁺(2i, 2), several infinite families of packings of 2^k-dimensional subspaces of real 2ⁱ -dimensional space are constructed, some of which are shown to be optimal packings. A certain Clifford group underlies the construction and links this problem with Barnes-Wall lattices, Kerdock sets and quantum-error-correcting codes.
