Abstract
In 2012, Andrews and Merca proved a truncated theorem on Euler's pentagonal number theorem, which opened up a new study on truncated theta series. In particular, some results on a truncated identity of Guass have been proved. In this article, we provide a new combinatorial interpretation of the truncated identity of Gauss in terms of the minimal excludant non-overlined part of an overpartition.
