How is random state updated after calling np.random.shuffle()? and how is it impacted by the length of the list to be shuffled?

How is the random state updated after calling np.random.shuffle()? and how is it impacted by the length of the list to be shuffled?

Here is the experiment:

np.random.seed(3)
print(np.random.get_state()[0],str(np.random.get_state()[1][:5]))
delta = 7
for t in [3,7,8, 9, 10]:
    print('-'*20)
    x = np.power(2, t)
    np.random.seed(3)
    a =np.arange(x-delta)
    np.random.shuffle(a)
    print(x-delta, np.random.get_state()[0],str(np.random.get_state()[1][:5]))
    np.random.seed(3)
    a =np.arange(x)
    np.random.shuffle(a)
    print(x, np.random.get_state()[0],str(np.random.get_state()[1][:5]))
    np.random.seed(3)
    a =np.arange(x+delta)
    np.random.shuffle(a)
    print(x+delta, np.random.get_state()[0],str(np.random.get_state()[1][:5]))

and the result:
