Fun fact: there are only two in that are equal to the sum of their factorials of their digits. (Ex 145: 1!+4!+5!= 1+24+120=145
First one to find the other one wins
Aside from the trivial 1 and 2, I can only find less than 1,000,000 is
40585
Though it seems likely that there could be others near multiples of 9!
