[seqfan] Re: What are the possible digit-sums for Fibonacci numbers?

[israel at math.ubc.ca]

Well yes, Fibonacci(n) mod 10^k will be periodic, but it will always take 
values of 0 mod 10^k. It's likely that (for n > 0) these will have lots of 
other digits making the digit sums large, but I don't see any prospect of 
controlling those.

Cheers,
Robert
