I think it should be in OEIS,  but also the sequence p-180,  because I
think traditionally (ie, in other similar instances) it is most often the
smallest member of the run that is recorded.

Btw I  am quite confident that p-180 is a subsequence of several sequences
already in the OEIS
(The same is probably true for the sequence of your p's, but potentially
only half as much ... well,  I hope you get what I mean... )
