Abstract

The main object of this paper is the construction of BIBD’s with 6k11 and λ=1. These balanced incomplete block designs can be simply constructed from some associated group divisible designs with the number of groups being a prime power, and it is these group divisible designs that are constructed directly. Other related designs are discussed.
