EXAMPLES:
    sage: G = Sp(4,GF(7))
    sage: G._gap_init_()
    'Sp(4, 7)'
    sage: G
    Symplectic Group of rank 2 over Finite Field of size 7
    sage: G.random_element()
    [1 6 5 5]
    [2 1 4 5]
    [1 2 4 5]
    [4 0 2 2]
    sage: G.order()

Return the symplectic group of degree n over R.

EXAMPLES:
    sage: Sp(4,5)
    Symplectic Group of rank 2 over Finite Field of size 5
    sage: Sp(3,GF(7))
    Traceback (most recent call last):
    ...
    ValueError: the degree n (=3) must be even
