The smallest gauge group that can accommodate such a symmetry among its subgroups is SO(5).
The second function of the second [Z.sub.2] basis vector [b.sub.2] is to break the untwisted observable symmetry gauge group from SO(12) x SO(4) to SO(10) x U[(1).sup.3].

Syed Raza Ali Shah, et al, study, showed that surgically induced corneal astigmatism was lower at one week postoperatively in the 23 gauge group (p=006) compared with the 20 gauge group (p=.001).
The four electroweak generators of the SM local gauge group SU[(2).sub.L] x U[(1).sub.Y] are typically labeled [W.sup.+], [W.sup.0], [W.sup.-], and [B.sup.0], but they can be defined equivalently as the quaternion generators i, j, k and b.
of California-San Diego) investigate the global in time regularity of the Yang-Mills equations on high dimensional Minkowski space with compact matrix gauge group G.
Theorem 1.1 can be used to help determine the homotopy types of certain gauge groups. In general, if G is a topological group, X is a space, and P [right arrow] X is a principal G-bundle, then the gauge group G (P) of the bundle is the group of G-equivariant automorphisms of P which fix X.
In addition, the field [PSI] transforms in the adjoint representation adj of some gauge group and [[PHI].sup.I] in some representation R of the gauge group.
Since the [a.sub.LR]-interaction is not invariant under the standard electroweak gauge group, it must be proportional to an SU(2)[.sub.L] X U(1) breaking parameter.
Highlights of the show are the ``Rudlow'' layout from the West Wales ``O'' Gauge Group, ``Temple Dean'' an ``N'' Gauge layout from Warley MRC and ``Pricklegate,'' a Southern Railway layout from Aberaeron.
