@tonwood - are you trying to tell me something?
@johncarlosbaez Maybe I'm trying not to tell you something.

@tonwood - In that case you would have succeeded.

@tonwood That right here is an alphabet!

This is very cool!
Here are representatives of the 45 orbits of these figures under the group D_4 (the eight rotations and reflections that are isometries of a square), so no pair of these 45 figures are rotations/reflections of each other.

@lisyarus Or rather a syllabary.
My motive in listing these figures was to design a script made from a limited repertoire of elements, without the sameness of Tengwar. And syllabaries are under-represented in fantasy scripts, though they are the most common stage after logographies.

@tonwood interesting idea to limit it to exactly six. I guess at least that excludes a certain hate speech symbol

@Farbs Fixing the number makes for inherent error-detection; and using exactly half maximizes the set of choices (before weeding out the disconnected).

These two sure 𝑙𝑜𝑜𝑘 like mirror images to me... -

So if I was trying to construct, say, a set of unique wooden objects that could be rotated and flipped over, it would only contain one of that pair.
Similarly, the last two figures in the original post’s third-last row look like they are duplicates, but one has a column of white space on the left, the other has it on the right.

@gregeganSF @tonwood I guess I'll leave the "whitespace is significant" to the Python programmers...
