Comments

Some numbers in this sequence are very rare in actual occurrence: In the 5700000-year cycle for Gregorian Easter dates, 311 occurs 1152 times, 678 occurs 688 times and 1045 occurs only 96 times (the first occasion between the years 31083 and 31103).

Does every large enough number appear in this sequence? - Charles R Greathouse IV, Jul 14 2012
