FieldInd

FieldInd[e]
gives the value of the discrete logarithm of e.
  • With p a primitive element of the field associated with the element e, the value of the discrete logarithm of e is the integer n such that pnEquale.
  • FieldInd is defined only if PowerListQ has been set True for the field.
  • FieldInd[0] gives -Infinity.
