M. J. Halm, Sequences

Digitally expand perfect numbers so that each digit becomes a term in the new sequence.

E.g., a(10)= 8 because 8 = 10th digit in the perfect number sequence (A000396): 6, 28, 496, 8128, ...

Cf. A007376, A000396.

Sequence in context: A059629 A082577 A098686 * A062771 A249919 A254868

Adjacent sequences: A079715 A079716 A079717 * A079719 A079720 A079721
