Equation 4 · Part 9 · Standardising the Record: How Writing Became Evidence
Ending index or upper bound: n
What this part means
This label says where the repeated addition, multiplication, or accumulation stops. It sets the last term or end of the range.
Its job in the formula
n appears in the bound of this product. The bound states where the repeated operation starts, ends, or which values it includes.

The passage around this formula
It is tempting to model manuscript transmission as pure decay. If is the probability that generation i of a copy reproduces a given passage faithfully, then fidelity after n generations of independent copying is . which for any constant per-generation fidelity below one falls exponentially in n . The model is illustrative and its value lies in the assumption it exposes rather than in any number it produces. It assumes errors accumulate…

Σ adds a collection of terms. Π multiplies them. The lower and upper labels tell you which terms belong to the collection.
