In the figure, I wonder that your math things are valid

I mean, 1) input 80 x 80 x 4 -- conv. w/ 8 x 8 x 4 x 32, stride 4 --> output 19 x 19 x 32 (because (80 - 8) / 4 + 1) => your result was 20 x 20 x 32 2) input 10 x 10 x 32 -- conv. w/ 4 x 4 x32 x 64, stride 2 ---> output 4 x 4 x 64 (because (10 - 4) / 2 + 1) => your result was 5 x 5 x 64

3) and...
input 3 x 3 x 64 -- conv. w/ 3 x 3 x64 x 64 --> your result was 3 x 3 x 64 (is this possible?)

am I wrong? Since I am a newbie on this area, if I misunderstood, please teach me.

because padding = ‘SAME’
