I was trying the example in the documentation: sage: k = GF(2) sage: k.extension(x^1000 + x^5 + x^4 + x^3 + 1, 'a') However, this gives the error: UnboundLocalError: local variable 'E' referenced before assignment How do I fix this? 2021-03-18 17:20:56 +0100 received badge ● Scholar (source) 2021-03-18 16:29:24 +0100 commented question Finite Field Extension Is there any other way I can specify a finite field modulo a particular irreducible polynomial? 2021-03-18 16:02:33 +0100 asked a question Finite Field Extension Finite Field Extension I am using SageMath version 9.2.
