EXAMPLE

40063 is separated from both the next lower prime and the next higher prime by 24;
104207  24 = 104183 is prime, 104207 + 24 = 104231 is prime, and 104207 is the only prime between 104183 and 104231.


MAPLE

for i from 1 by 1 to 40000 do if ithprime(i+1) = ithprime(i) +24 and ithprime(i+2) = ithprime(i) + 48 then print(ithprime(i+1)); fi; od; # Zerinvary Lajos, May 04 2007
