FORMULA

A prime p belongs to the sequence iff p/log(p) - q/log(q) > 1 where q is the preceding prime

EXAMPLE

79 is okay since 79/log(79) - 73/log(73) = 1.065... > 1

PROGRAM

(PARI) { default(realprecision, 100); n=0; s=2/log(2); forprime (p=3, 26203, if ((r=p/log(p)) - s > 1, write("b060769.txt", n++, " ", p); ); s=r; ) } [From Harry J. Smith (hjsmithh(AT)sbcglobal.net), Jul 11 2009]
