Almost Fibonacci Collection

Fibonacci Statue in Pisa, *plus.maths.org


0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181... Ok, You get the idea... 


I just came across a couple of odd references to things that produce Fibonacci like sequences, at least for a short while...

It started when I posted a note on the 89th day of the year (You do the math) that 89 is the fifth Fibonacci prime and the reciprocal of 89 starts out 0.011235... (generating the first five Fibonacci numbers) (which I found at the Prime Curios page.  (Ok footnote here, I didn't realize until just recently that if the nth Fibonacci number is prime, then n is also prime, with one exception. but not the converse)

Don S McDonald (@McDONewt) then sent me another... 69 Choose 5 = 1 1 2 3 8 5 13 which is so nearly perfect...
Now I'm thinking there must be more of these... so fire away... Send them in and I'll make a collection we can all share..
