Gaps of size 2, 4, and (conditionally) 6 between successive odd composite numbers occur infinitely often [PDF]
Notes on Number Theory and Discrete MathematicsThe infinite sequence of gaps (first differences) between successive odd composite numbers contains only the numbers 2, 4, and 6. We prove that, for any natural number k, the sequence of gaps contains infinitely many k-tuplets of consecutive gaps all ...
