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 re(2): three MORE

9! - 4! + 1! - 0 = 362857 is the best that I have found, but I was working with numbers less than 10 for any powers.
I like your tactic.
