## Abstract Let __L__ denote the set of positive integers that do not divide 6. In 1983, Drake and Larson determined all positive integers __v__ such that there is a proper PBD(__v__,__L__) with one exception, namely, the integer __v__โ=โ30. (Recall that a PBD is __proper__ if there is no block tha
Batten, L.M., The nonexistence of finite linear spaces with v = n\* points and b = nz + n+ 2 lines, Discrete Mathematics 115 (1993) 11-15. We show that any finite linear space on u = n\* points and b = n2 + n + 2 lines has nd 4. We also describe all such spaces.
