代码A——NestList[FromDigits[IntegerDigits[#, 8], 9] &, 8, 24]
{8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 27, 30, 33, 37, 41, 46, 51, 57, 64, 81, 100, 121}

代码B——NestList[FromDigits[IntegerDigits[#, 24], 27] &, 24, 36]/3
{8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 27, 30, 33, 37, 41, 46, 51, 57, 64, 72, 81, 91, 102, 114, 128, 144, 162, 182, 204, 256, 315, 381, 455, 565}

代码C——NestList[# + Floor[#/8] &, 8, 36]
{8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 27, 30, 33, 37, 41, 46, 51, 57, 64, 72, 81, 91, 102, 114, 128, 144, 162, 182, 204, 229, 257, 289, 325, 365}
