So the Alt
Zeta 2 function is associated with the (infinite) sum of reciprocals of the
unique number sequences associated with the general polynomial equation (x –
1)

^{n}= 0.
So for example the unique digit sequence associated with (x – 1)

^{3}= 0 is,
1, 3, 6, 10, 15, …

And the corresponding (infinite) sum of reciprocals is

1 + 1/3 +
1/6 + 1/10 + 1/15 + … = 2.

So I refer
to this sequence as Alt ζ

_{2}(3).
Now in
general terms, I represent the Zeta 2 function as ζ

_{2}(s_{2}) = 1 + s_{2}^{1}+ s_{2}^{2}+ s_{2}^{3}+ …
And where n
is an integer > 2, s

_{2 }= 1/(n – 1) and ζ_{2}(s_{2}) = Alt ζ_{2}(n).
Therefore,
when n = 3, s

_{2 }= 1/2;
So ζ

_{2}(1/2) = 1 + (1/2)^{1 }+ (1/2)^{2 }+ (1/2)^{3 }+ … = 2;
Thus ζ

_{2}(1/2) = Alt ζ_{2}(3), and in general terms ζ_{2}{1/(n – 1)} = Alt ζ_{2}(n).
Now I have
commented before on the fact that Alt ζ

_{2}(n) represents numbers (as denominators) that result from an ordered summation of natural numbers.
Thus for
example with respect to Alt ζ

_{2}(3) = 1 + 1/3 + 1/6 + 1/10 + 1/15 + …
1 = 1

3 = 1 + 2 = 1 + (1 + 1)

6 = 1 + 2 + 3 = 1 + (1 + 1) + (1 + 1 + 1)

10 = 1 + 2
+ 3 + 4 = 1 + (1 + 1) + (1 + 1 + 1) +
(1 + 1 + 1+ 1) .

So we can
see a definite order to these numbers where the denominator of the k

^{th}term represents the sum of the first k natural numbers.
And when n
> 3 the denominator of the k

^{th}term still represents a compound ordered sum involving the first k natural numbers.
For example
when n = 4, the (infinite) sum of unique associated reciprocals is,

1 + 1/4 +
1/10 + 1/20 + 1/35 + …

Now if to illustrate, we
take the denominator of the 3rd term it can be shown to represent a compounded
ordered sum entailing the first 3 natural numbers.

So 10 = 1 +
3 + 6 (the sum of the first 3 denominators terms of the previous sequence for n
= 3.

Thus 10 = 1
+ (1 + 2) + (1 + 2 + 3).

However
there is another remarkable feature associated with these denominators
entailing the ordered product of natural numbers.

So for
example 3 = 3/1;

6 = (4 * 3)/(1 * 2);

10 = (5 * 4
* 3)/(1 * 2 * 3);

15 = (6 * 5
* 4 * 3)/(1 * 2 * 3 * 4).

So starting
with the initial value of denominator (= n/1), subsequent values are given as {(n + 1) * n}/(1 * 2),
{(n + 2) * (n + 1) * n}/(1 *2 * 3), {(n + 3) * (n + 2) * (n + 1) * n}/(1 * 2 * 3 * 4), ...

In fact we
can express these in an alternative fashion which shows that each number (as
denominator) represents a unique combination.

So in
general terms nC

_{r }= the number of r possible combinations taken from a group of n items.
Now each
number as denominator likewise represents a unique combination with respect to
a certain number of items (defined by the value of n

_{1}) = n_{1}!/{r!(n_{1}– r)!}
So for example
6 = (4 * 3 * 2 * 1)/(2 * 1)(1 * 2) =
4!/{2!(4 – 2)!}

Thus in
general terms, n

_{1}= (n + k – 2) where k = cardinal number of k^{th}term and n represents the denominator of the 2^{nd}term in the infinite series associated with (x – 1)^{n}= 0, r = k – 1 and n_{1}– r = n – 1 respectively.
Thus in terms of our definitions, n

_{1}!/{r!(n_{1}– r)!} = (n + k – 2)!/{(k – 1)! * (n – 1)!}
Thus when n = 3, the denominator of the 4

^{th}term (i.e. where k = 4)
= (3 + 4 – 2)!/(3! * 2!)

= 5!/(3!* 2!) = (5 * 4)/(1 * 2) = 20/2 = 10.

So the denominator, i.e. 10 represents the total number of
possible combinations of 3 taken from 5 items.

And by definition the denominator of every term, in the
infinite series of reciprocals of the unique numbers associated with (x – 1)

^{n}= 0, represents a unique combination of numbers.
This then provides a ready means for calculating any term in
the infinite sequence for a given value of n.

Thus for example when n = 6, the denominator of the 5

^{th}term,
= (6 + 5 – 2)!/(5 – 1)!(6 – 1)! =
9!/(4! * 5!)

= (9 * 8 * 7 * 6)/(1 * 2 * 3 * 4) = 3024/24 = 126.

Thus the 5

^{th}term of the (infinite) sum of reciprocals based on the unique numbers associated with
(x – 1)

^{6}= 0 = 1/126.
Thus to sum up, the Alt ζ

_{2}(n) series can be defined both in terms of an ordered sum of the 1^{st}k natural numbers (to a given term k) relating to the denominators of the terms of its associated series and an ordered product of the natural numbers representing the factorials of numbers involved in the respective unique combinations associated with (n + k – 2)!/(k – 1)!(n – 1)!
And the importance of these formulations in turn relates to
the fact that every individual term of the Zeta 1 (Riemann) function i.e. ζ

_{2}(s_{1}) with s_{1}> 1 - both in its sum over natural numbers and product over primes formats - can be expressed in terms of the Alt ζ_{2}(n) series.
