Angles, in degrees, can be any number -infinity ... +infinity, but their use repeats after 360, so the question is, can all number from 0..360 be represented as a prime number mod 360.

ex:
start out with the primes below 360:

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293 307 311 313 317 331 337 347 349 353 359

if you continue up, the first angle that isn't represented above and is prime would be 409 ( 409 - 360 = 49 ), 409 is prime but 49 isn't, so 49 is added to the list.

so... How many angles can be represened as a distinict result of a prime number mod 360?

did a edit, that help? I'm sure a lil' perl script on a prime number txt file would do teh trick... might try it out later tonight
