We study the action of the group PGL( m,A ) on the projective space PG( m − 1, A ) over a finite commutative local algebra A in order to construct a class of divisible designs, denoted by D m (d,A) , which is the classical one of 2‐designs (of points and of flats of fixed projective dimension) in the case where A is a field. We also study the constructed divisible designs with particular care for the case where d = m − 1. © 1995 John Wiley & Sons, Inc.
