Requiring that amount of supersymmetry forces X to be a spherical space form, whence isometric to the quotient of the round 7-sphere by a freely-acting finite subgroup of SO(8). the triads and quaternions with which he loaded his sentences. To make use of the example from Subsection 4. quaternions, and double groups by Simon L. Then the folded complex numbers become cosets rather than pairs of reals. Si H est un sous-groupe normal de G, le quotient G/H est abélien si et seulement si H contient le groupe dérivé de G [3]. They find applications in several knowledge fields, namely physics, geometry, image processing, computational biology, computational chemistry, computer graphics, and computer games. One can get rid of this nonuniqueness by way of a quotient construction -- specifically, by taking the quotient C/2iZ of the complex numbers by the additive normal subgroup 2iZ, and treating the resulting quotient group as the folded complex numbers.
