Clever!

I've done a challenge a bit like this: create all numbers from 1-200 using 4 4s and the following mathematical operators: +, -, /, x, ! (factorial), !! (double factorial), INT, MOD, SQRT, ^ (power). You can't do squares etc. - if you use powers the number has to be raised to its fourth power (or 4x4th power etc.).

It is much harder than it looks like!
