x^{42} \to \frac{2-3a^7-7a^{15}}{a^{21}}\\  x^{44} \to -\frac{2+11a^{18}}{a^{22}}\\  x^{30} \to -\frac{-2+3a^5+5a^9}{a^{15}}\\  x^{66} \to -\frac{-2+3a^{11}+11a^{27}}{a^{33}}  x^{69} \to \frac{3+23a^{20}}{a^{23}}  \end{equation}  It seems that for numbers with $3$ prime factors, the coefficient of the largest power of $a$ in the numerator is the power of the second largest power of $a$. Although only a few numbers have been checked so far.
