 OFFSET 1,1 COMMENTS Problem proposed by and terms through a(8) by Fred Schneider. No other terms < 10^12. a(26)-a(29) > 1.4*10^14. - Giovanni Resta, Jul 13 2013 LINKS Table of n, a(n) for n=1..25. Carlos Rivera, Prime Puzzle 696: 1801 EXAMPLE Primes 83, 89, 97, 101, and 103 have gaps 6, 8, 4, and 2, resp. Each of the first four positive even integers is used exactly once, so a(4)=83.
