Finiteness of \(R\)-equivalence groups of some adjoint classical groups of type \(^2D_3\).
For an algebraic group \(G\) defined over a field \(F\), let \(G(F)/R\) be the group of \(R\)-equivalence classes introduced by Manin. Examples of \(G\) are given such that \(G\) is connected, linear, adjoint, not defined over a global field, not quasi-split, while \(G(F)/R\) is finite and non-trivial.
