✦ Synopsis

Zhu, L., B. Du and X. Zhang, A few more RBIBDs with k =5 and A = 1, Discrete Mathematics 97 (1991) 409-417. It has been shown that there exists a (u, 5, l)-RBIBD for any positive integer u = 5 (mod 20) with 147 possible exceptions. We show that such designs exist for 34 of these values.

The existence of a (q, k, 1) difference family in GF(q) has been completely solved for k = 3. For k = 4, 5 partial results have been given by Bose, Wilson, and Buratti. In this article, we continue the investigation and show that the necessary condition for the existence of a (q, k, 1) difference fa

For a prime power q = 1 (mod k(k-1)) does there exist a (q, k, 11 difference family in GF(q)? The answer to this question is affirmative for k=3 and also for k>3 provided that q is sufficiently large (Wilson's asymptotic existence theoremt but very little is known for k > 3 and q not large enough.

mation of the ( Z ) isomer supports the assumption that in compound 13 (and probably also in 12) the substituents at the noncoordinated C=C double bond are arranged cis. The rhodium-containing product of the reaction of 8 or 13 with acetic acid is the chelate complex 17,[\*] which can be reconverted
