考虑了整数群子集自身和及自身差势的问题,基于对前人给出的几类整数群上超差集合构造的研究,通过对典型有限和超差集合A1的有限分解,即A1={0,2}∪{3,7,11,…,4k-1}∪{4k,4k+2}∪{4},其中k是不小于3的正整数,证明给出了整数群上一类无限的和超差集合的构造,使集合的势从有限上升为无限,拓展了前人的理论成果。

补充资料：子集
集合论的基本概念之一。如果集a的任一元素都是集b的元素，则称集a为集b的一个子集，记作ab或ba，读作“a包含于b”或“b包含a”。如果a是b的子集，且b中至少含有一个不属于a的元素，则称a是b的“真子集”，记作ab或ba。任一集合都是它本身的子集，空集是任何集合的子集。
