[seqfan] Re: New sequences from generalized Fibonacci sequence

>The associative arrays of a and b are transposes of each other and the
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?
