$"the effective capacitance between the points A and B is "(3C)/2$

enter image source here

$"figure-1"$

$"the points C,E,G are the same points(colored red)"$

$"the points A,D are the same points(colored blue)"$

$"the points F,B are the same points(colored green)"$

$"simplify the figure-1 like figure-2"$

enter image source here

$"figure-2"$

$C_1,C_2,C_3" have connected as parallel"$

$C_1,C_2,C_3 rArr C_A=C+C+C=3C$

$C_4,C_5,C_6 " have connected as parallel"$

$C_3,C_4,C_5 rArr C_B=C+C+C=3C$

$C_A and C_B " have connected as serial"$

$C_("AB")=(3C)/2$
