what is the logic of GPIO numbers in the ESP32-S2?

Looking at the datasheet I see that the GPIO numbers are not continuous.
Is there any logic for it?

For example there are no GPIO 22-34 or 43-44

That is not the same for other ESP32

Thanks!

Hm, I never noticed. Probably a bunch of pins that got cut from the design when we decided the packaging for the chip, but for some reason we never updated the pin numbers.
