Let Vi (i = 1, 2) be a set of size vi. Let D be a collection of ordered pairs (b1 , b2 ) where bi is a ki-element subset of Vi. We say that D is a mixed t-design if there exist constants Ξ» (j 1 ,j 2 ) (0 ≀ ji ≀ ki, j1 + j2 ≀ t) such that, for every choice of a j1 -element subset S1 of V1 and every c

Let ~ be a 2- (v,k,2) design with k finite. When v is finite it is well known that blocktransitivity implies point-transitivity, whereas for infinite designs the relationship between the numbers of point and block orbits is unknown. We find bounds for the number of block and point orbits and provide
