Abstract
Existing studies show that the symmetric division deg (SDD) index deserves to be treated as a useful and practicable molecular descriptor, preferable to some of the more widely used ones. The primary purpose of this review is to summarize the existing extremal results and bounds for the SDD index. Several open problems regarding the aforementioned index, arising from the known results, are also proposed.
