we already had 120
right, but sometimes I find shorter solutions

128 = 4 x 4 x (4 + 4)129 = (4^4 + sqrt4) / sqrt4

131 and 133 = ? (can be done with 5 4s)134 = 44 / .4 + 4!

also read this
http://www.math.hmc.edu/funfacts/ffiles/10006.8.shtml
they say it's possible to get all numbers until 112 with only
the four arithmetic operations (+,x,-,/), concatenation (44 is ok and uses up two 4's), decimal points (using 4.4 is ok), powers (using 4^4 is ok), square roots, factorials (using 4! is ok), and overbars for indicating repeating digits (e.g., writing .4 with an overbar would be a way of expressing 4/9)

44 / 0,(4) = 99
99 + 24 = 123

Then I've got the long missing
107 !
107 = (4! + 4!) / .4 overbar - ld(sqrt(4))
