At-design is a pair, whereXis av-element set andis a set ofk-subsets ofX, called blocks, with the property that everyt-subset ofXis contained in exactlyblocks. At-designis said to be-resolvable ifcan be partitioned intosuch that eachis ans-design, further, if eachis also-resolvable, then such an-resolvablet-design is called-doubly resolvable. In 1980, Hartman constructed a (2, 3)(1, 1)-doubly resolvable 3-(v, 4, 1) design forand a (2, 3)-resolvable 3-design. In this paper, we construct (2, 3)(1, 1)-doubly resolvable 3-designs for all positive integersn.
