63. In this paper, in line with the usage in the literature, by topology of the universe we mean the topology of its spatial section.
64. For instance, the reported non-Gaussianity in cosmic microwave background (CMB) maps [7] along with the small power of large-angle fluctuations [8], and some features in the power spectrum [7-9] are all large-scale anomalies which have been suggested as potential indications of a universe with non-trivial topology [10, 11]. See Ref. [14] for a detailed discussion on these anomalies.
65. The extent to which a nontrivial topology may or may not be detected has been discussed in references [17].
66. These values are taken as typical and for the sake of comparison with the results of Refs. [18]. We note, however, that our general conclusions hold regardless of the precise value for α and its uncertainty.
