but I'm not sure that I was justified in choosing 'E'

Basically,
You move the triangle set to the centre like you did with the first column, and then, superimposing the triangle set on the first set, it will be noticed that there is no pairing up, so the second triangle set triangles become added. If that makes sense?😅

I just think the middle box is wrong one of the triangles should be dark

^^

ben

If you fix that it’s a trivial xor to combine any two

if these two become added

Horizontal or vertical

they do not equal the other box

<:towelsweat:552805059042344960>

I said that’s an error

if the middle box is wrong, then it has nothing to do with the placement of the triangles

The top right triangle should be dark

no Fuguer you don't understand what I'm saying

For the center vox

Well, the orientation of the result does not matter. It only matters insofar as where the remainder colours should be

no Ben

if you add those two boxes

it does NOT

get you the third one

I don't see how your method applies to this column at all

Ah, there are two black ones

Yeah, this column is weird

yes, this was my original theory

and the one that I guessed based off of

It’s xor

now we're turning them?

It works for all of them

I mean dark to dark and light to light

the thing is, if its an error, then its easy and my original theory was correct, and we don't need to worry about transposing and cancelling or anything like that, you just add the two lesser boxes and get the big box

its that simple

It’s an error simple xor

Bruh they could have aligned this shit. <:PepoFacts:586190890519887882>

Yeah but adding two lesser boxes to get big box is equivalent to xor

yes

That’s why xor is a beautiful operation

its the difference between addition and subtraction...

which is to say
