4!+4!+4+sqrt(4)=54

BTW, what number are we going to? 4444!?

100 I believe

Oh right, first post. Gotta think about 55...

I've seen way over 100, but 4444 might be taxing!

I said 4444!, but that's impossible since 4444!-1 is impossible, as well as 4444!-2, 4444!-3... =)

EDIT: Actually, (4^(4^(4^4))))! is larger...

55 is possible with 5 fours or 4 fives...

55 is very similar to 53 - just got to get 10 from the last 2 fours!

After some work, how's about (4reciprocal + root4 - 4)/ .4 = 55?

So arctan(4/4) + 4/.4 = 55 then?

(4/.4 + 4)x4 = 56

That's the one I had in mind.
There are several ways of getting most of them, but ISTR that a couple in the 70's are tough. The arctan(4/4) is one I haven't seen used elsewhere(though perfectly legal!) - that might make those easier.

arctan(degrees)[4/4] + 4!/sqrt(4) = 57
