  Observations of protoplanetary disks around binary and triple star systems
suggest that misalignments between the orbital plane of the stars and the disks
are common. Motivated by recent observations of polar circumbinary disks, we
explore the possibility for polar circumtriple disks and therefore polar
circumtriple planets that could form in such a disk. With n-body simulations
and analytic methods we find that the inclusion of the third star, and the
associated apsidal precession, significantly reduces the radial range of polar
orbits so that circumtriple polar disks and planets can only be found close to
the stellar system. Outside of a critical radius, that is typically in the
range of 3-10 times the outer binary separation depending upon the binary
parameters, the orbits behave the same as they do around a circular orbit
binary. For some observed systems that have shorter period inner binaries, the
critical radius is considerably larger. If polar circumtriple planets can form,
we suggest that it is likely that they form in a disk that was subject to
breaking.
