Identification of confounded design and its interactions

Kane has discussed a simple method for identifying the confounded interactions from 2n factorial experiments when a replication consists of (1) two blocks and (2) more than two blocks. It should be noted that Kane's method holds only for (1) regular design and (2) when one interaction is confounded. In the present investigation, we proposed a new way of identifying the confounded designs and the confounded interactions in 2n factorial experiments. Furthermore, the same method is extended to 3n and Sn factorial experiments.
