How to declare a finite field element resulting from a Prime Power in Pari/ɢᴘ ?

[Laël Cellier <lael.cellier@gmail.com>]

Let’s talk first about the equivalent SageMath code : I’ve a finite 
field declared as ff= GF(q) where q is the prime power of degree 12.

Given a finite field element that SageMath printf as |0*z12^11 + 
0*z12^10 +

+ 0*z12^8 + 0*z12^7 + 0*z12^6 + 0*z12^5 + 0*z12^4 +

+ 0*z12^2 + 0*z12 + 0, how to set a variable belonging to ff to such 
static value in Pari/ɢᴘ ? Since finite field elements in such cases are 
polynomes…|
