We derive a previously unknown lower bound of 41 for the frequency ofs max = 8 of an E( s 2 )‐optimal and minimax‐optimal supersaturated design (SSD) with 20 rows and 76 columns. This is accomplished by an exhaustive computer search that uses the combinatorial properties of resolvable 2 − (20, 10, 36) designs and the parallel class intersection pattern method. We also classify all nonisomorphic E( s 2 )‐optimal 4‐circulant SSDs with 20 rows ands max = 8 .
