Mendelsohn三元系大集(LMTS)和可迁三元系大集(LDTS)是两类有向设计的大集,它们的存在性问题已完全解决,若在以上的两类设计中要求有序对(x,x)也出现,则称这样的设计为extended Mendelsohn三元系大集(LEMTS)和extended可迁三元系大集(LEDTS)。
2) large set of pairwis
extended可迁三元系大集
1.

1.
The kind of large set above-mentioned is called large set of pairwise disjoint extended Mendelsohn triple systems(LEMTS) if oriented pair(x,x) occurs in them.
若在以上的设计中要求有序对(x,x)也出现,则称这样的设计为extended Mendelsohn三元系大集(LEMTS)。
2.
The two kinds of large set above-mentioned are called large set of pairwise disjoint extended Mendelsohn triple systems (LEMTS(v)) and large set of pairwise disjoint extended transitive triple systems (LEDTS(v)) respectively if oriented pair (z, x) occurs in them.
Mendelsohn三元系大集(LMTS)和可迁三元系大集(LDTS)是两类有向设计的大集,它们的存在性问题已完全解决,若在以上的两类设计中要求有序对(x,x)也出现,则称这样的设计为extended Mendelsohn三元系大集(LEMTS)和extended可迁三元系大集(LEDTS)。
补充资料:大迁
1.指迁都。 2.日至于女纪之称。古人认为日出于旸谷﹐入于虞渊﹐中经昆吾﹐是谓正中;至于鸟次﹐是谓小迁;至于女纪﹐是谓大迁。见《淮南子.天文训》。今本《淮南子》作"小还"﹑"大还"﹐《初学纪》卷一引作"小迁""大迁"。王念孙《读书杂志.淮南三》:"小还﹑大还﹐当为小迁﹑大迁﹐字之误也。迁之为言西也。日至昆吾谓之正中;至鸟次则小西矣﹐故谓之小迁;至女纪则大西矣﹐故谓之大迁。"
