[zak seidov]

OK, it's more simple:
Eric's < 500
0,1,2,3,4,5,6,7,8,9,12,18,21,24,27,36,42,45,48,54,
63,72,81,84,102,108,111,112,114,117,126,132,133,135,
144,152,153,156,162,171,192,195,198,201,204,207,209,
216,222,224,225,228,234,243,247,252,261,264,266,285,
288,306,308,312,315,322,324,333,336,342,351,364,372,375,378,392,396,399,402,405,407,408,414,423,432,441,444,448,465,468,476,481,486
