Border symmetric rank conjecture for monomials

Let $x_0,\ldots,x_n$ be variables and let $0\leq\alpha_0\leq\cdots\leq\alpha_n$. Write $\operatorname{bsrk}$ for border symmetric rank. Border symmetric rank conjecture. For these exponents, one has

$$\operatorname{bsrk}\left(x_0^{\alpha_0}\cdots x_n^{\alpha_n}\right)=\prod_{i=0}^{n-1}(\alpha_i+1).$$

The statement concerns the still-open problem of computing the border symmetric rank of monomials. The cited attribution is to Oeding (2016).
