846

Is the number 846 possible or necessary? DuncanHill (talk) 22:25, 31 March 2019 (UTC)

Yes, it exists. 846 seconds is less than a quarter of an hour. 846 inches is just over 70 feet. Georgia guy (talk) 01:03, 1 April 2019 (UTC)

I think 846 is possible, but not necessary. I've never used it. Bubba73 ^{You talkin' to me?} 03:42, 1 April 2019 (UTC)

Let's abolish all unnecessary numbers (as determined by Bubba's Criterion). Then we can really get down to business solving the mysteries of the universe without all that impedimenta blocking our view. -- Jack of Oz ^{[pleasantries]} 08:38, 1 April 2019 (UTC)
