In statistical planning of experiments, super-simple designs are the ones providing samples with maximum intersection as small as possible. Super-simple group divisible designs are useful in constructing other types of super-simple designs which can be applied to codes and designs. In this article, the existence of a super-simple (5, 4)-GDD of group type gu is investigated and it is shown that such a design exists if and only if u≥5, g(u - 2)≥12, and u(u - 1)g2 ≡ 0 (mod 5) with some possible exceptions.
