Smallest possible transparency size on disk

I'm new to Gimp and experimenting trying to make the smallest possible transparent image.

As an Off-topic aside, I run local DNS in my LAN and redirect spammy ad domains to localhost so I don't have to look at their garbage when ad blockers fail, like with flash content. My 1 x 1 image will be wedged in place so I don't see "page cannot be displayed blah blah" in my browser.

So far I've been able to slim down to a 108 byte png or a 43 byte gif using indexed mode. Is this as good as it gets or can the image get smaller using some other technique?

Thanks!

I managed to 1x1 PNG down to 81 bytes when using 1bit paletted image and to 73 bytes by using 24bit.

I tried to create a new 1x1 image, set it to 1 bit (b/w), saved it as GIF file (without the "Created with GIMP" comment) and it's only 35 bytes small.
