%N Primes of the form F(i)^2 + F(j)^3, where F() are Fibonacci numbers.

%F For example, a(2)=17 because 17=2^3+3^2

%t f = Table[ Fibonacci[ i ], {i, 1, 100} ]; g = Union[ Flatten[ Table[ f[ [ i ] ]^2 + f[ [ j ] ]^3, {i, 1, 100}, {j, 1, 100} ] ] ]; Table[ g[ [ Select[ Range[ 1000 ], PrimeQ[ g[ [ # ] ] ] & ] ] ] ]
