So, a normal 2\u2010pseudomanifold triangulates a connected closed 2\u2010manifold. But,\nnormal <jats:italic>d<\/jats:italic>\u2010pseudomanifolds form a broader class than triangulations of connected closed <jats:italic>d<\/jats:italic>\u2010manifolds\nfor <jats:italic>d<\/jats:italic> \u2265 3. Here, we classify all the 8\u2010vertex neighbourly normal 3\u2010pseudomanifolds. This gives a\nclassification of all the 8\u2010vertex normal 3\u2010pseudomanifolds. There are 74 such 3\u2010pseudomanifolds,\n39 of which triangulate the 3\u2010sphere and other 35 are not combinatorial 3\u2010manifolds. These 35\ntriangulate six distinct topological spaces. As a preliminary result, we show that any 8\u2010vertex 3\u2010pseudomanifold is equivalent by proper bistellar moves to an 8\u2010vertex neighbourly 3\u2010pseudomanifold. \nThis result is the best possible since there exists a 9\u2010vertex nonneighbourly 3\u2010pseudomanifold which\ndoes not allow any proper bistellar moves.<\/jats:p>","DOI":"10.1155\/2008\/254637","type":"journal-article","created":{"date-parts":[[2008,9,18]],"date-time":"2008-09-18T14:55:53Z","timestamp":1221749753000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Three\u2010Dimensional Pseudomanifolds  on Eight Vertices"],"prefix":"10.1155","volume":"2008","author":[{"given":"Basudeb","family":"Datta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nandini","family":"Nilakantan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,18]]},"reference":[{"key":"e_1_2_6_1_2","unstructured":"BagchiB.andDattaB.
