Is there any interesting theorem or result from l-functions or modular forms that covers this result? I am learning about them and I find the topic fascinating. I discovered them watching https://www.peakmath.org/quest-for-f1 https://www.peakmath.org/quest-for-f1 videos on youtube. Also worth exploring: http://lmfdb.org http://lmfdb.org
