Mathematica: cpu = 0.152519 (sec), leaf count = 61 $$\text{left {left {y(x)to text {DifferentialRoot}left ({unicode {f818},unicode {f817}}unicode {f4a1}left {-b-unicode {f817} a unicode {f818}(unicode {f817})+unicode {f818}^{(5)}(unicode {f817})=0,unicode {f818}(0)=c\_1,unicode {f818}'(0)=c\_2,unicode {f818}''(0)=c\_3,unicode {f818}^{(3)}(0)=c\_4,unicode {f818}^{(4)}(0)=c\_5right }right )(x)right }right }}$$

Maple: cpu = 0 (sec), leaf count = 0 $$\text{hanged}$$
