The Cookson Hills series is the series similar to the Flint Hills series, but with numerator instead of :
(Pickover 2002, p. 268). It is not known if this series converges since can have sporadic large values.
The plots above show its behavior up to . The positive integer values of giving incrementally largest values of are given by 1, 2, 5, 8, 11, 344, 699, 1054, 1409, 1764,
2119, ... (OEIS A004112), corresponding to
the values 1.85082, 2.403, 3.52532, 6.87285, 225.953, 227.503, ....
