Prime Polynomials (2..511)

Binary values expressed as polynomials can readily be manipulated using the rules of binary arithmetic.

The table below shows all prime polynomials from 2..511 (these are unrelated to prime decimals!). Try the LRS link to see the corresponding Linear Recursive Sequence.

Polynomials leading to maximum length sequences are shown highlighted (*) and are called primitive polynomials.

With the MATLAB Communications Toolbox the primitive polynomials of order N may be found using primpoly( N, 'all'). For example: 
>> primpoly ( 6, 'all' )

ans =

67  91  97  103  109  115
Which is a list (in decimal) of all the primitive polynomials of order 6 identified in the table below.

For larger numbers, try the Online Factoring Tool
