Next Pythagorean prime which does not "use" 1^2 and 2^2 is A002144(6)=41=4^2+5^2, hence a(2)=41.
Next Pythagorean prime which does not "use" 1^2, 2^2, 4^2 and 5^2 is A002144(9)=73=3^2+8^2, hence a(3)=73.
Next Pythagorean prime which does not "use" 1^2, 2^2, 3^2, 4^2, 5^2 and 8^2 is A002144(16)=149=7^2+10^2, hence a(4)=149.
