#We find all primitive subgroups of $GL(10,5)$ with parameters $e=2$, $a=5$
#In the notations of Theorem 5.1, if $H$ is a primitive solvable subgroup, then it possesses a series

#$$1<U<F<A<H,$$

#where $U$ is cyclic of order $5^5-1$, $F=U\circ E$ and $E$ is extraspecial of order $2^{1+2}$, moreover
#in this case $|H:A|$ divides $2$. Since $b=1$ divides $a=3$, Lemma 5.3 implies that there is up to conjugation there is one $F$, and
#$N_{L}(F)/F\simeq Sp(2,2)\simeq S_3$, where $L=C_{GL(6,5)}(U)$.
