COMMENTS

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
