I am trying to run the following example from S-Boxes and Their Algebraic
Representations - Cryptography (sagemath.org)
<https://doc.sagemath.org/html/en/reference/cryptography/sage/crypto/sbox.html>
from sage.crypto.sbox import SBox
S = SBox(12,5,6,11,9,0,10,13,3,14,15,8,4,7,1,2)
S.component_function(1).autocorrelation()
When I run the code I get the error copied here:
