Let D be a definite quaternion algebra such that its center has degree d over Q. A subgroup G of GLn(D) is absolutely irreducible if the Q-algebra spanned by the matrices in G is Dn×n. The finite absolutely irreducible subgroups of GLn(D) are classified for nd ≤ 10 by constructing representatives of the conjugacy classes of the maximal finite ones. Methods to construct the groups and to deal with the quaternion algebras are developed. The investigation of the invariant rational lattices yields quaternionic structures for many interesting lattices.
