Al, Max and Michael,
Thank you for your most useful comments. As I have only recently started
contributing sequences to OEIS and do not yet know all the ropes, you have
given me considerable food for thought.
My first mistake is that I forgot that I had already submitted the sequence
specified in my last email. It is A166468. Next, the offset in A166373 is
specified as 1 but should be 2 as n >= 2. This
would have an impact on some of Max's comments.
I have been submitting sequences discovered during investigations I have
carried out over the last few years. One such investigation was to examine
the characteristics of
(Sum of the quadratic non-residues of prime(n) - Sum of the quadratic
residues of prime(n)) / prime(n). I discovered that this was equivalent to
(sum ( floor (j^2 / prime(n))), j = 1:prime(n) - 1) - floor ((prime(n) -
2)(prime(n) - 1) / 3) and that this could be extended to the naturals. This
is why 1 <= j <= n - 1 has significance in A166373.
I have realised from Al's comments that my focus should be more on providing
some value to the research community than simply providing new sequences.
Consequently, I would like the
following sequences to be withdrawn from the OEIS:
