Marion's finiteness conjecture for rigid triangle generation

Let $G$ be a simple algebraic group over an algebraically closed field of characteristic $p>0$. For a positive integer $m$, let $j_m(G)$ be the dimension of the subvariety of elements of order dividing $m$, and call a triple $(a,b,c)$ rigid for $G$ when

$$j_a(G)+j_b(G)+j_c(G)=2\dim G.$$

Call $(a,b,c)$ hyperbolic when $1/a+1/b+1/c<1$. Marion's conjecture. Fix a prime $p$. If $(a,b,c)$ is a rigid hyperbolic triple of primes for $G$, then there are only finitely many positive integers $r$ such that the finite quasisimple group $G(p^r)$ is $(a,b,c)$-generated.

The conjecture concerns the finiteness of field extensions yielding triangle generation in the rigid case, extending the known results for rank-two groups. Its resolution status is not specified in the supplied text.
