2019-04-10 00:33:28 -0500 | asked a question | How to access serial number corresponding to each element in $GF(2^3)$? I would like to access serial number corresponding to each element in $GF(2^3)$? Corresponding to each serial number, I can access the element in $G(2^3)$ as follows: This provides : I would like to get the reverse process which will provide seral number corresponding to each element in $(2^3)$, that is, Is there any such way? |

2019-04-09 21:08:20 -0500 | asked a question | How to access index value of an element in $GF(2^3)$? I would like to access the index value of the corresponding element in $GF(2^3)$. The following code generates all the elements with a unique index value, but if the field size is very large, then it takes a very long time to generate all the elements with their corresponding index value. So I don't like to generate all the elements at a time. When I call a particular element this will return the corresponding index value of this particular element. Suppose, If an element $p(x)$ is in enumerate(F), then it should return the corresponding index value of $p(x)$. How can I do this? |
