| // In this package, the CRC polynomial is represented in reversed notation, |

| // or LSB-first representation. |

| // LSB-first representation is a hexadecimal number with n bits, in which the |

| // most significant bit represents the coefficient of x⁰ and the least significant |

| // bit represents the coefficient of xⁿ⁻¹ (the coefficient for xⁿ is implicit). |

| // For example, CRC32-Q, as defined by the following polynomial, |

| // x³²+ x³¹+ x²⁴+ x²²+ x¹⁶+ x¹⁴+ x⁸+ x⁷+ x⁵+ x³+ x¹+ x⁰ |

| // has the reversed notation 0b11010101100000101000001010000001, so the value |

| // that should be passed to MakeTable is 0xD5828281. |
