The Dec 2020 issue of the Amer Math Monthly has an article Desmond MacHale, Are there more finite rings than finite groups?, Amer. Math. Monthly, 127:10 (2020), 936-938. showing that there are infinitely many n such that there are more groups with n elements than rings with n elements. He gives one example, n = 36355, and asks if this is the smallest such n. This is a sequence not yet in the OEIS! Anyone care to investigate? These are the n such that A000001(n) > A027623(n).
