A census of genus-two 3-manifolds up to 42 coloured tetrahedra

Abstract: We improve and extend to the non-orientable case a recent result of Karábaš, Maličký and Nedela concerning the classification of all orientable prime 3-manifolds of Heegaard genus two, triangulated with at most 42 coloured tetrahedra

“…Catalogues of 3-manifold rigid 5 crystallizations up to 32 vertices have already been generated and completely classified ( [15], [18], [19], [5]). Complete classification was also obtained for genus two 3-manifolds admitting a crystallization with at most 42 vertices ( [6]).…”

“…is isomorphic to the abelianized group of m, n, k . Therefore, (m, n, k) = (5, 3, 2) or (7,3,2) implies that abelianization of m, n, k is trivial. Thus, M 5, 3, 2 and M 7, 3, 2 are homology spheres, in fact, M 5, 3, 2 is the Poincaré homology sphere.…”

“…Since m, 2, 2 ( ∼ = Q 4m ), P 24 := 3, 3, 2 , P 48 := 4, 3, 2 and P 120 := 5, 3, 2 are finite groups, by the proof of elliptization conjecture of Perelman, M m, n, k is spherical, i.e., M m, n, k ∼ = S 3 / m, n, k for these groups m, n, k . It is not difficult to prove that, the abelianization of m, n, k ∼ = Z ⊕ H for some group H if and only if (m, n, k) = (6, 3, 2), (4,4,2) or (3,3,3). Therefore, in these three cases, the 3-manifold M m, n, k has a handle and in all the other cases, M m, n, k is handle-free.…”
