As I said, it depends on the definition. The octetts mention in the
Wikipedia
article are also prime octetts that repeat -- like the one I was using. For
all of them the Hardy-Littlewood conjecture applies somehow.
For example, the first pattern in the Wikipedia article repeats as follows:
[11,13,17,19,23,29,31,37]
[15760091,15760093,15760097,15760099,15760103,15760109,15760111,15760117]
[25658441,25658443,25658447,25658449,25658453,25658459,25658461,25658467]
[93625991,93625993,93625997,93625999,93626003,93626009,93626011,93626017]
[182403491,182403493,182403497,182403499,182403503,182403509,182403511,182403517]
[226449521,226449523,226449527,226449529,226449533,226449539,226449541,226449547]
[661972301,661972303,661972307,661972309,661972313,661972319,661972321,661972327]
[910935911,910935913,910935917,910935919,910935923,910935929,910935931,910935937]
[...]
It repeats less often than the one I'm using. One might speculate, because
it is less symmetric(?).
Wikipedia articles are sometimes incomplete or not quite correct, even in
mathematics.
