[seqfan] Re: New sequences from generalized Fibonacci sequence

[Frank Adams-Watters]

That follows immediately from the definition of the associative array. 
The second column of the associative array is the indices of the second 
occurrence of n in the sequence a, etc.

first column of the b's associative array, 1, 4, 12, 28, 55, 96, etc.,
seems to be A006000.


Does {1, 4, 12, 28, ...} also give the index of the first occurrence of 
n
in your sequence a, or is it just a coincidence for the first four 
terms?
