I have a series of numbers ranging from PE00001 to PE99999. Sample/Snippet below (descending order): PE00445 PE00444 PE00442 PE00438 PE00437 PE00434 PE00432 PE00428 PE00424 PE00423 PE00420 PE00418 PE00417 PE00416 PE00414 PE00412 PE00411 PE00410 PE00405 PE00404 PE00403 PE00400 PE00398 PE00397 PE00393 PE00386 PE00383 PE00381 PE00377 PE00374 PE00352 PE00350 PE00348 PE00344 PE00339 PE00334 PE00332 PE00330 PE00328 PE00326 PE00323 PE00284 PE00283 PE00281 PE00280 PE00279 PE00278 PE00277 PE00276 PE00275 PE00273 PE00270 PE00269 PE00268 PE00267 PE00266 PE00265 PE00264 PE00263 PE00262 PE00261 PE00260 What would be the best approach to have mathematica show me what STRINGS are missing from this series?
