Description (last modified by alexjbest)

As per the text after (2.8) in (Arul, Vishal, Alex J. Best, Edgar Costa, Richard Magner, and Nicholas Triantafillou. “Computing Zeta Functions of Cyclic Covers in Large Characteristic.” The Open Book Series 2, no. 1 (January 28, 2019): 37–53. https://doi.org/10.2140/obs.2019.2.37.) the q-power frobenius is what we need to find the action of, before we used the p-th, see the new doctest for a failing example.
