Find the largest number, a single string of only digits - without radix or exponent, that can be equated to a mathematical expression that uses no variables and where each and every digit, 0 to 9, is used but once in the equation. Provide the equation.
Mathematical symbols and functions are permitted, yet limit each to less than the arbitrary number of ten.
If limited to digits 0 to 5, a possible answer, for example, could be:
5!/(4 - 3) = 120.

(In reply to 6 digits (3 x10^6) by Leming)

I like yours as well :

Look Virginia, no computers:

(6!)^2+0!-7=518394

 

LETS TRY FOR 7 DIGITS STRING

to morrow , maybe
