Query: Dualising the Dual Standard Model   We discuss how the dual standard model and the dualised standard model are
complementary theories. That is, how their implications have no overlap, whilst
together they explain most features of the standard model. To illustrate how
these two theories might be combined we consider the dual standard model in a
theta vacuum. Whilst there are issues to be considered, the dual standard model
does then appear to become naturally dualised. This supports an origin of a
dual formulation of the standard model through the properties of SU(5) solitons
in a theta vacuum.
