* What is the semicolon?

* How does this expand to:

2n(n²+n)(n³+n)...(n^k+n)

Thank you in advance.

Doesn't it say right there?
the q-Pochhammer symbol (a; q)_n

Good eyes.
Thank you.

There is sigma as the symbol for sum of series, there is the equivalent symbol for product of series ( what is that symbol called? ).

Is there an equivalent symbol/operator for the power of series?

Replacing the word "sum" or "product" with "power" in Wolfram alpha does not return expected results.

Thank you in advance.

Capital pi.

Correct me if I am wrong, but it should be possible to represent the power-of-series using iteration notation.

Would appreciate confirmation or negation.

Thank you in advance.

The concept seems absent on the net:

are we talking geometric series, arithmetic series, harmonic series?, or power series? are they finite, or infinite ? I once saw a math.stackexchange question about powers using arithmetic progressions in order for example ( not quite the same but interesting non the less).

?= (n^1+n)^(n^2 +n)^.... [k times]

iterated functions are so like the functions of LL or

for LL it's :

but starting with x=4

for generating the next mersenne number you can use:

starting at x=0 ( or x=1 depending on what you think of 0 being a mersenne number, under one of the definitions) . I guess, I don't get where you are going.
