This paper introduces a persistence puzzle involving two sports clubs with a somewhat intertwined history. As one might assume, the implications of the puzzle go far beyond a mere plea for a precise metaphysical analysis of certain perplexing quandaries regarding sports clubs and represents a challenge for our everyday understanding of social groups. To overcome the supposed impediment to the puzzle, as a starting point, I will accept the assumption that these entities are both social groups and abstract artifacts and will further argue that they are temporal abstract objects. Since temporal objects are in time, it will be determined that the cause of the conundrum is the seeming inability to correctly account for the I-relation between the temporal parts, and I will elaborate on why such an explanation is required. Ultimately, I’ll introduce the notion of I-shifting, which will explain how temporal abstract objects persist through time and consequently solve the puzzle.

本文介绍了一个持久性难题，涉及两个历史交织在一起的体育俱乐部。正如人们可能认为的那样，这个谜题的含义远远超出了对体育俱乐部某些令人困惑的困境进行精确形而上学分析的单纯请求，它代表了对我们对社会群体的日常理解的挑战。为了克服这个难题的假设障碍，作为起点，我将接受这些实体既是社会群体又是抽象人工制品的假设，并将进一步论证它们是时间抽象对象. 由于时间对象在时间中，将确定难题的原因是似乎无法正确解释时间部分之间的 I 关系，我将详细说明为什么需要这样的解释。最后，我将介绍I-shifting的概念，这将解释时间抽象对象如何随着时间持续存在并最终解决这个难题。
