How to test polynomial 157464165547 ?

[HelloRayH]

Would you please show me how to test the (63,30) BCH code? ------->The (64,30) block code generator polynomial is denoted g(D) = (1+ D) g'(D), where g(D)is the generator polynomial 157464165547 (octal notation) of a primitive binary (63,30) BCH code.
