  Tangetially related: For the people who don’t know, I found out recently that x!! isn’t the same as (x!)! (repeated factorial), in fact, !! is a LOT less big than repeated factorial.

  For example, while 30!! is 4.286 x 10^16 (so a number with 17 digits), doing 30! and then ! the result of that, would be a number with an unfathomable 10^33 digits.

      x!^(n) is the product of the positive numbers congruent to x (mod n) and less than or equal to x. put more simply x*(x-n)*(x-2n)…

      so 10!!! = 10*7*4*1

      No clue. Wolfram Alpha interprets it as (10!!)!, so I assume !!! isn’t an established operator, unlike the very unintuitive !!.

  I think 30 should look better than 15.
  Like 7 legs on each side and one in the back as mechanical afterburner?

    The other guy was making a maths joke

    “30!!” Is 30 double factorial and therefore that very large number

    I assume it’s like my third leg, which I mostly just let drag. Occasionally, I’ll throw it over my shoulder like a continental soldier.

    I’m sure they’d love to have a spare. Accidents happen, you know?
