We characterize the proper t-wise balanced designs t-(v,K.l) for t 2 3, A = 1 and v 5 16 with at least two block sizes. While we do not examine extensions of S(3,4,16)'s, we do determine all other possible extensions of S ( 3 , x , v ) ' s for v 5 16. One very interesting extension is an 5(4,{5,6},
Let k be a field of characteristic p and let # # Aut k (k((t))). For m 0 define i m =v t (# p m t&t)&1. We show that if p |3 i 0 is and i 1 <( p 2 & p+1) i 0 then there exists an integer b such that i m =i 0 +bp+bp 2 + } } } +bp m for all m 1. 1997 Academic Press 1 Γ Gal(K(#)ΓK) Γ Aut 1 (K(#)) Γ 1 Γ
