A partial Steiner triple system of order n is sequenceable if there is a sequence of length n of its distinct points such that no proper segment of the sequence is a union of point-disjoint blocks. We prove that if a partial Steiner triple system has at most three point-disjoint blocks, then it is sequenceable.

测序部分 Steiner 三重系统

如果存在长度为 n 的不同点的序列，使得该序列的任何适当段都不是点不相交块的并集，则 n 阶部分 Steiner 三重系统是可排序的。我们证明，如果一个部分 Steiner 三元组最多有三个点不相交的块，那么它是可排序的。
