Sp(n) is the group of the quaternionic linear automorphisms acting from the left on a right quaternionic n-dimensional vector space preserving a positive definite Hermitian form on it. Sp(ri) Sp(l) is the group Sp(n) x 5p(l)/{(l, 1), (-1,-1)}. If we identify Hn with R4n, the following left action on a right quaternionic n
