Hyperovals in projective planes turn out to have a link with t‐designs. Motivated by an unpublished work of Lonz and Vanstone, we present a construction for t‐designs and s‐resolvable t‐designs from hyperovals in projective planes of order . We prove that the construction works for . In particular, for the construction yields a family of 5‐ designs. For numerous infinite families of 4‐designs on points with block size can be constructed for any . The construction assumes the existence of a 4‐ design, called the indexing design, including the complete 4‐ design. Moreover, we prove that if the indexing design is s‐resolvable, then so is the constructed design. As a result, many of the constructed designs are s‐resolvable for . We include a short discussion on the simplicity or non‐simplicity of the designs from hyperovals.

投影平面上的超卵形体与t设计有联系。由龙泽和范斯通的未发表的作品的启发,我们提出了一个建设牛逼-designs和小号-resolvable牛逼-designs从顺序射影平面超卵形。我们证明该建筑工程适用于。特别是对于 该建筑产生了5个家庭 设计。对于 上的4设计的无穷系列 点与块大小 可以为任何构造 。该构造假设存在4个 设计,称为索引设计,包括完整的4‐ 设计。此外,我们证明了如果索引设计s ^ -resolvable的,那么所构造的设计。其结果是,许多构造设计都是小号-resolvable为。我们将简短讨论超级椭圆形设计的简单性或非简单性。
