Example

For n = 2,...,12, the fractions are 2/1, 3/1, 2/1, 5/1, 3/2, 7/1, 2/1, 3/1, 2/1, 11/1, 4/3, so that
A218993 = (2, 3, 2, 5, 3, 7, 2, 3, 2, 11, 4, ... );
A219093 = (1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 3, ... );
A219094 = (1, 1, 2, 1, 1, 1, 4, 3, 5, 1, 1, ... );
A219095 = (6, 12, 15, 18, 20, 21, 24, 28, 30, 35, 36, ... ).
