Variable -- specify a name for the generator of a Galois field

Variable -- specify a name for the generator of a Galois field

Variable => x -- an option used with GF, to specify a symbol to be used as a name for the generator of the Galois field.

Functions with optional argument named Variable :

GF(..., Variable) -- specify a name for the generator of a Galois field

integralClosure(..., Variable => ...) -- Sets the name of the indexed variables introduced in computing the integral closure of a reduced ring.

minPres(..., Variable) -- specify a name for the generator of a Galois field

minPresIdeal(..., Variable) -- specify a name for the generator of a Galois field
