Description: Narcissistic numbers are numbers whose individual digits raised to the power of the total number of digits can be added together to create the original number. So, for 153, that means 1^3 + 5^3 + 3^3 = 153. How big can they get? And do they even matter? No... and yes. GH Hardy criticized the concept of narcissistic numbers as being purely recreational with no practical application, but isn't amusement the point?! Relax, GH. Have a little number fun. #shorts
