First term that is not a multiple of 17 (A008599) is 273, which is one more than 272 = 16 * 17. In hexadecimal, 272 is 110, which having a single 0 next to a 1, disqualifies it from this sequence. - Alonso del Arte, Oct 16 2016

EXAMPLE
255 in hexadecimal is FF, a run of two Fs, hence 255 is in the sequence.
273 in hexadecimal is 111, a run of three 1s, hence 273 is in the sequence.
291 in hexadecimal is 123, three distinct single digits, so 291 is not in the sequence.
