Sequence A020995 with Fibonacci numbers whose digit sums equals index might
be interesting for you. For base 10 lovers and haters you can use Fib(10)=55
(with digit sum 10). It is similar to Harshad numbers too. The last number
Fib(2222) is big:

A004090 is interesting there too.
These numbers you have as Lucas numbers (A020997) and in base 12 (A020996
and A020998) and base 11 (A025490 and A025491) in OEIS too. In base 11 the
biggest numbers are very large, with index Fib(1636597) and Lucas(2528952).
But possibly less interesting - who wants to calculate in base 11...

I just do not have the time to participate seriously in that paper.

Well, as long as you and others can get at it.
There is only one paper.
I mailed the link three times because I didn't realize my mailer had
truncated the links the first two times.
