- A fundamental identity in the representation theory of the partition algebra is $n^k = \sum_λ f^λm_k^λ$ for $n \geq 2k$, where $λ$ ranges over integer partitions of $n$, $f^λ$ is the number of standard Young tableaux of shape $λ$, and $m_k^λ$ is the number of vacillating tableaux of shape $λ$ and length $2k$. Using a combination of RSK insertion and jeu de taquin, Halverson and Lewandowski constructed a bijection $DI_n^k$ that maps each integer sequence in $[n]^k$ to a pair of tableaux of the same shape, where one is a standard Young tableau and the other is a vacillating tableau. In this paper, we study the fine properties of Halverson and Lewandowski's bijection and explore the correspondence between integer sequences and the vacillating tableaux via the map $DI_n^k$ for general integers $n$ and $k$. In particular, we characterize the integer sequences $\boldsymbol{i}$ whose corresponding shape, $λ$, in the image $DI_n^k(\boldsymbol{i})$, satisfies $λ_1 = n$ or $λ_1 = n-k$.
