>>87
Interestingly in the i = 10^8 case my sequence seems to be off, and even very small values such as 100 it is incorrect. I suppose I must have misinterpreted the sequence.
(map (lambda (e) (hofstadter (sub1 (expt 10 e)))) '(0 1 2 3 4 5 6 7 8))
=> (1 69 5808 528364 50927960 5029664750 500941310658 50029799244875 5000942659057950)
