A. Karttunen, Scheme functions for computing A066425 and related sequences.

a(1) = 1, a(n) = a(n-1) + A068058(n-1)

Also a(n) = A068057(2^(n-1)) = A068739(n+1)-2*A068739(n)+1 and for n > 1, a(n) = A066425(n) - A068055(n-1). Cf. A068221, A068222.

Sequence in context: A081988 A030783 A136969 this_sequence A108868 A156913 A138461

Adjacent sequences: A068056 A068057 A068058 this_sequence A068060 A068061 A068062
