Query: Degree complexity of birational maps related to matrix inversion:
  Symmetric case   For $q\geq 3$, we let $\mathcal{S}_q$ denote the projectivization of the set
of symmetric $q\times q$ matrices with coefficients in $\mathbb{C}$. We let
$I(x)=(x_{i,j})^{-1}$ denote the matrix inversion, and we let
$J(x)=(x_{i,j}^{-1})$ be the matrix whose entries are the reciprocals of the
entries of $x$. We let $K|\mathcal{S}_q=I\circ J:\mathcal{S}_q\rightarrow
\mathcal{S}_q$ denote the restriction of the composition $I\circ J$ to
$\mathcal{S}_q$. This is a birational map whose properties have attracted some
attention in statistical mechanics. In this paper we compute the degree
complexity of $K|\mathcal{S}_q$, thus confirming a conjecture of Angles
d'Auriac, Maillard, and Viallet in [J. Phys. A: Math. Gen. 39 (2006),
3641--3654].
