a(n) = A007953(A011545(n)). - Reinhard Zumkeller, Oct 30 2003

The partial sums to 10^k, k>=0: 4, 44, 480, 4479, 44897, 449336, 4499937, 45002885, 449989731, .... - Robert G. Wilson v, Sep 16 2007

If the sequence were to start with an initial term a(0) = 0, its first differences would reproduce the complete sequence of digits of Pi. - M. F. Hasler, Jan 19 2015
