Order Equal to 215

If $\mid G \mid = 215 = 5 \times 43$ then G can not be simple by Theorem 1.2. This same result can be applied to a large number of orders in our given range. The list of these orders eliminated where $\mid G \mid \ne 2n$, for n-odd, would be as follows;

201, 203, 205, 209, 213, 215, 217, 219, 221, 235, 237, 245, 247, 249, 253, 259,
265, 267, 287, 291, 295, 297, 299, 301, 303, 305, 309, 319, 321, 323, 327, 329,
335, 339, 341, 355, 365, 371, 377, 381, 391, 393, 395
