r/math on Reddit: Interesting phenomenon with 10 factorial
August 7, 2023 -
I saw a post on this sub a few days ago (sorry, I tried to find it with no luck) where someone pointed out that: 1*2*3*4*5*6*7*8*9*10 = 1*2*3*4*5*6*7*6*5*4*3*2*1 It makes sense because the first 1 through 7 cancel out, then the prime factorization of 8*9*10 (2⁴ * 3²\ * 5) matches that for 1-6.
My question is: are there other examples of this? To formalize, for any two real number m and n, such that m<n, how many examples are there where n! = m! * (m+1)! (The above example of course being m=6 and n=10)
My gut intuition is that it would have to be during a decent length string of composite numbers.

August 7, 2023What’s 10!! Someone’s saying it’s (10!)! But I thought it was 10x8x6x4x2 or something like that
Depends on context. “!!” is sometimes used to denote the product skipping every other number like you’re saying, but it could also just be someone literally writing “the factorial of the number 10!” More on reddit.com
