Abstract
Screening designs are useful for situations where a large number of factors (q) is examined but only few (k) of these are expected to be important. It is of practical interest for a given k to know all the inequivalent projections of the design into the k dimensions.
In this paper we give all the inequivalent projections of inequivalent Hadamard matrices of orders 16 and 20 into k = 3, 4 and 5 dimensions, as well as their frequencies.
