171 =
172 = 44 * 4  4 173 = 174 = 44 * 4  √4 Yes, I took the two easy ones ... I'm still trying the other two Last fiddled with by petrw1 on 20070307 at 03:29

So, we need 171 before proceeding further. :) Last fiddled with by cheesehead on 20070308 at 10:08

I did not find anything without gamma...
171 = gamma(gamma(4)) / √.4~  4/.4~ 173 = gamma(gamma(4)) + (4!  .4~)/.4~ Edit: going further: 175 = ((4 + 4!) / .4) / .4 176 = 44 * (√4 + √4) Last fiddled with by Andi47 on 20070308 at 18:05

We move on after 177:
177 = ((√4 / .4)!  √4) / √.4~ 178 = (4 * 44) + √4 179 = ((4 + √4)!  4) / 4 180 = 4 + (4 * 44) Last fiddled with by fetofs on 20070322 at 01:41 Reason: using fancy sqrt symbol

Some better solutions (note that I consider too many square roots to be ugly):

165 = 44 / (.4 * √.4~) 170 = (4! + 44) / .4 Last fiddled with by fetofs on 20070322 at 01:41

Suggestion
I suggest you allow two additional functions, sum and subfacorial.
S4 = 4+3+2+1= 10 (I do not have a sigma on my computer) !4= 9 These are sometimes accepable in this game.

181 = ((√4 / .4)! + √.4~)/√.4~

181 = (4 + (4 + sqrt(4))!) / 4
182 = ((4 + sqrt(4))! / 4) + sqrt(4) 183 = (sqrt(4) + (sqrt(4) / .4)!) / sqrt(.4~) 184 = 4 * (sqrt(4) + 44) Is 185 possible?

185 = gamma(gamma(4)) + √(√(√(4^4!))) + gamma(√4)) Quote:
gamma(n) = (n1)! examples: gamma(√4) = 1! = 1 gamma(4) = 3! = 6 gamma(gamma(4)) = 5! = 120

You can also get 185 by using the sum and subfactorial functions ad follows:
(sum(sum4))*sqrt (4 subfactorial)+sum4+sum4
