Quantum entanglement rapidly becomes unwieldy to calculate as the number of particles
and the dimension of the spaces associated to those particles increase. One meaningful approach
which simplifies that analysis is the restriction to subsets of states which obey some physically
relevant symmetry. In this thesis, entanglement properties of totally permutation-symmetric,
translationally invariant, and party-site symmetric states are examined, as well as those of small
bond-dimensional matrix product states.
