  The two and three-body contacts are central to a set of univeral relations
between microscopic few-body physics within an ultracold Bose gas and its
thermodynamical properties. They may also be defined in trapped few-particle
systems, which is the subject of this work. In this work, we focus on the
unitary three-body problem in a trap, where interactions are as strong as
allowed by quantum mechanics. We derive analytic results for the two and
three-body contacts in this regime and compare with existing limiting
expressions and previous numerical studies.
