Constructions of doubly resolvable Steiner quadruple systems

摘要

An SQS(v) is said to be doubly resolvable if it has two orthogonal resolutions and denoted by DRSQS(v). In this paper, we give two new constructions, i.e., doubling construction and doubly resolvable MPCQS construction. We also give some new results of doubly resolvable SQS(v).
