摘要
The set of self-mapping degrees of S^3-geometry 3-manifolds in[2]have some mistakes when the fundamental group of the 3-manifold is D4n^*,O48^*,D'n·2q or T'8·3q.So we need to make this errata.The self-mapping degrees of all closed and oriented 3-manifolds are listed in[1]and[5].The table of spherical case in[5]is mostly quoted from[2].The results in[5]which do not involve the corrections made here still valid.The results in[5]involving the corrections made here should be also changed.
