Query: The Magueijo-Smolin Group in Doubly-Special Relativity is Linear in Five
  Dimensions   Magueijo and Smolin have introduced a modification of the Lorentz group for
the momentum-space transformations in Doubly-Special Relativity. As presented
the group is non-linear, but we show that it is a group of fraction-linear
transformations in 4 dimensional real projective space. We pass to the
associated 5 dimensional linear space and identify the subgroup as a conjugate
of the ordinary Lorentz group, giving the conjugating matrix. Taking the dual
of the 5-space, we identify a subgroup as the Lorentz transformations about a
point different to the origin.
