1,2

This sequence is the dual, of sorts, of the k-tuple abundance record-holders sequence. The numbers in this sequence correspond to the k-tuple abundance of the numbers in the record-holders sequence.

Table of n, a(n) for n=1..12.

a(5) = 31 because 31 is the first k-tuple abundance that beats a(4) = 8.

Cf. A081699, A081705.
