Is there a more succinct way to notate this?
$$(n!)((n-1)!)((n-2)!)\cdots(2!)(1!)$$
for clarification, if I had asked a similar question, how to succinctly notate:
$$(n)(n-1)(n-2)\cdots(2)(1)$$
I would be looking for this as an answer: $n!$
I think the most informative way would be to rewrite the product into
$$\prod_{i=1}^n i^{(n-i + 1)}$$
It is easy to see that yours is
$$n^1(n-1)^2(n-2)^3\cdots 3^{n-2}2^{n-1}1^{n}=\prod_{i=0}^{n-1}(n-i)^{i+1}.$$
