[seqfan] Re: 0^n in A097135

[Alonso Del Arte]

Yes, F(n) stands for the Fibonacci numbers. I was unaware of A7, and I'm not
sure I agree with its definition. However, my assertion that 0^0 is
indeterminate comes not from any deep mathematical understanding on my part,
but was simply my repeating what Mathematica told me.

Given that a(n) = 3F(n) starting with a(0) is already in the OEIS as
A022086, it is perhaps not so concerning that the definition of A097135 is
needlessly complicated by the distraction of 0^0.
