A study of BIB designs with replications 11 to 15
C. Radhakrishna Rao · 1961
The combinations of parameters for BIB designs with replications 11 to 15 have been listed and the actual solutions of the cyclic type have been given in a number of cases. It may be observed that Fisher and Yates (1953) give the solutions to BIB designs up to 10 replications only.
