Hello:

I am a new user on GAP and I have a few questions:

- is there a way to convert from a polynomial to vector? The Polynomial

in Chap. 19 converts vector to poly, but I can't find a command to go

the other way.

- do I refer to an individual element in a vector just the same as I do

in Pascal or C? (eg. vec[0] or vec[1]?)

- is it possible to do interactive inputs? For example, I want to

display:

Please enter a number from 1 to 10:GAP will then await for the user to enter a number and put the number

in a variable (say "input").

- I defined a variable by using:

alpha = Z(256)^1;which means that alpha is first non-zero Galois field element in

GF(256). From now if I want to a power of alpha I just go alpha^2.

Is it possible to display the name of this variable as "alpha" as well?

Currently the output is displayed as "Z(2^8)^26" or similar, which

reduces readability. I tried using:alpha.name := "alpha";but GAP complains about being a record or something to that effect.

Thanks,

MingS
