Query: Spin, Statistics, and Reflections, I. Rotation Invariance   The universal covering of SO(3) is modelled as a reflection group G_R in a
representation independent fashion. For relativistic quantum fields, the Unruh
effect of vacuum states is known to imply an intrinsic form of reflection
symmetry, which is referred to as "modular P_1CT-symmetry (Bisognano, Wichmann,
1975, 1976, and Guido, Longo, [funct-an/9406005]). This symmetry is used to
construct a representation of G_R by pairs of modular P_1CT-operators. The
representation thus obtained satisfies Pauli's spin-statistics relation.
