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.
