You may ask David W. Wilson.  He has computed
some of the following sequences:

a(1,n) : A000012 The simplest sequence of positive numbers: the all 1's 
sequence.
a(2,n) : A018892 Number of ways to write 1/n as a sum of exactly 2 unit 
fractions.
a(3,n) : A004194 Number of partitions of 1/n into 3 reciprocals of 
positive integers.
a(4,n) : A020327 Number of partitions of 1/n into 4 reciprocals of 
positive integers.
a(5,n) : A020328 Number of partitions of 1/n into 5 reciprocals of 
positive integers.
