r/math on Reddit: Interesting phenomenon with 10 factorial
August 10, 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.
