Alexei Kourbatov and Marek Wolf, Predicting maximal gaps in sets of primes, arXiv preprint arXiv:1901.03785 [math.NT], 2019.
EXAMPLE
The first two primes of the form 8k + 5 are 5 and 13, so a(1)=5. The next prime of this form is 29 and the gap 29-13=16 is a new record, so a(2)=13.
PROG
(PARI) re=0; s=5; forprime(p=13, 1e8, if(p%8!=5, next); g=p-s; if(g>re, re=g; print1(s", ")); s=p)
