The pf overlaps with 11, 13, 17, 19..........at 11........overlap is an important theme I think.....................the primes in the prime fund...........are 2, 3, 5, 7, 11...........................5 primes...............why is 11, 13, 17, 19 are important I think............b/c after 10...................a prime can only end in a 1, a 3, a 7 or a 9................ever............why?  2 cuts out half of the entire number line...........as a simple sieve............if u use 5 as another sieve........only those two primes.......cut out 60% of the number line beyond ten.........................no even number, other than 2 can ever be prime...............and no middle number in any ten digit 10 sequence........anything ending in a 5.........of course 2 and 5..............as sieves.........overlap at anything ending in a zero...............
