文摘In this article, we establish the existence of an LHMTS(mv) for v ≡ 2 (mod 6) and m≡ 3 (mod 6). Thus there exists an LHMTS(mv) if and only if v(v-1)m2 ≡ 0 (mod 3) except possibly for v=6, m≡ 1, 5 (mod 6) and m≠1. In the similar way, the existence of LHDTS(mv) is completely determined, i.e., there exists an LHDTS(mv) if and only if v(v-1)m2 ≡ 0 (mod 3).
