(((6!)/(4!))-3!)*1
6 factorial = 720
4 factorial = 24
3 factorial = 6
therefore ((720/24) = 30 and 30 - 6 = 24 and 24 * 1 = 24
Done it!

To the Walrus and any other interested parties,
I am new to the quiz and took the instructions literally. I have looked at last months quiz and pasted it in below.
------------------------------------------------------
In the last newsletter, I set you a Nubble puzzle :-
Using the basic operations of addition, subtraction, multiplication and division, construct the answer 1 by using all the numbers 1, 1, 1 and 5.
There are various solutions, such as 5x(1-1)+1=1.
------------------------------------------------------
So you see they have used brackets, and although they are not a function like ! is they weren't listed in the + - / and * signs either.
I don't know if it's the right way to do it but it got me the correct answer so I have entered into the quiz in the spirit of hope. If you like this sort of thing go to Simon Singh's website at http://www.simonsingh.net/ and join us.
Thanks for reading my blog and getting back to me.-

I liked your solution, though I suspect you don't need all the brackets ((I'm too lazy to check!)) and am only commenting on the absence of ! from their puzzle. Presumably, raising a number to a power would also be an allowable function as it depends only on the position and size of the digits, rather than using a function symbol?
I congratulate you on finding a solution to a sloppily defined puzzle!-

Your perfectly correct, all those brackets weren't required. Yes, I think powers would also be allowed although probably only 1,3,4 & 6. I tried that and got no-where.
So nice to hear from someone with such a positive response. Nice one!!
I looked at your site. I used to write and translate Z80 games in the late 80's, Spectrum and Amstrad stuff. "Great minds", and all that.

"Using + - / * and all the numbers 6,4,3,1 make the answer 24"
But that has no "!" in it...
