For p=7, (2^6-1)/(3*7) = 3 and 3 is not greater than 7.
For p=11, (2^10-1)/(3*11) = 31, which is greater than 11, so a(1)=31.
For p=13, (2^12-1)/(3*13) = 105 = 3*5*7 and 3 is not greater than 13.
For p=17, (2^16-1)/(3*17) = 1285 = 5*257 and 5 is not greater than 17.
For p=19, (2^18-1)/(3*19) = 4599 = 3^2*7*73 and 3 is not greater than 19.
For p=23, (2^22-1)/(3*23) = 60787 = 89*683 and 89 is greater than 23, so a(2)=89.
