Abstract
For all positive even integers , graphs of order with degree sequence \begin{equation*} S_{n}:1,2,\dots,n/2,n/2,n/2+1,n/2+2,\dots,n-1 \end{equation*} naturally arose in the study of a labeling problem in \cite{IMO}. This fact motivated the authors of the aforementioned paper to study these sequences and as a result of this study they proved that there is a unique graph of order realizing for every even integer . The main goal of this paper is to generalize this result.
