arcSin(degrees)[sqrt(4)/4]/sqrt(4) - 4 = 71

using arcsin(0.5) = 150 degrees as opposed to the principal value of 30

BTW, what number are we going to? 4444!?
After a bit of research, 2179 is apparently the first number without a known solution - so feel free to carry on!
(That list excluded trig functions whereas I didn't, so even 2179 might be possible.)
