converted to a polynomial depending on which bits are set. The max value of the polynomial with all bits set (11111111)hex is x⁸+x⁷+x⁶+x⁵+x⁴+x³+x²+x¹+1. Thus it follows that 25 that has only the first,4th and 5th bit set will be x⁵+x²+1.Multiplication of polynomial for the 3rd row is actually 02 in
