A Class Of Group Divisible Designs With Block Size Three And Index Lambda
AUSTRALASIAN JOURNAL OF COMBINATORICS(2010)
摘要
We investigate the existence of group divisible designs (GDDs) with block size three, group-type g(t)w(1) and index.. We prove that the elementary necessary conditions for the existence of such a GDD are also sufficient, which generalizes the result of Colbourn, Hoffman and Rees.
