A -semiframe of type is a -GDD of type , in which the collection of blocks can be written as a disjoint union , where is partitioned into parallel classes of and is partitioned into holey parallel classes, each holey parallel class being a partition of for some . In this paper, we will introduce a new concept of -perfect semiframe and use it to prove the existence of a 3-semiframe of type with even group size. This completes the proof of the existence of 3-semiframes with uniform group size.

完成块大小为 3 的半帧频谱
一个 - 类型的半帧 是一个 -GDD 类型 , 其中块的集合 可以写成不相交的并集 , 在哪里 被划分为并行的类 和 被划分成孔平行类,每个孔平行类是 对于一些 . 在本文中,我们将介绍一个新的概念 -完美的半帧并用它来证明类型的 3-semiframe 的存在 组大小均匀。这样就完成了具有统一组大小的 3-semiframes 存在的证明。
