Let V = V ( n, q ) denote the vector space of dimension n over GF ( q ). A set of subspaces of V is called a partition of V if every nonzero vector in V is contained in exactly one subspace of V . Given a partition of V with exactly a i subspaces of dimension i for 1≤ i ≤ n , we have , and we call the n ‐tuple ( a n , a n − 1 , …, a 1 ) the type of . In this article we identify all 8‐tuples ( a 8 , a 7 , …, a 2 , 0) that are the types of partitions of V (8, 2). © 2010 Wiley Periodicals, Inc. J Combin Designs 18: 462–474, 2010
