%N Possible number of weeks between two (Gregorian calendar) Easters.
%C 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).
%C Does every large enough number appear in this sequence? - _Charles R Greathouse IV_, Jul 14 2012

%e 311 is in the sequence because there exist two Easters (for example, between the years 7996 and 8002) that are 311 weeks apart.
