There is more than one logical order if you want it to be like base 3
But with that restriction I think there are only two.
...
WAIT.
I gave a bad hint.
□□▣ is last.

I don't know how well this puzzle will translate to a toot. Imagine each line is on a card:
□□▷
□□□
■■

□▷▣
▣

▣▷
□□■
□▷
▣▣
□□

▣□
□□▣
■□
▷
□▷□
□▷■
▣■
□▷▷Put them in order.
(The 5th graders could do it, but they did have a helpful example first... There may be more than one solution, but I think there is ONE really good order. Can you find it?)(I should also mention that every adult I've shown this to gives up. But I only showed it to two rather grouchy teachers.)
@futurebird Good puzzle. ‘The proof is left as an exercise for the reader.”

@futurebird I like this. When I teach people about bases, I try to break them free from the symbols having values, and we often end up having them do something in base 3 with circles, squares, and triangles.
Funny you should mention that.

Yeah this is harder without cards to move around and put in arrays. But I think it's still possible.
@futurebird i tried copypasting into a plaintext editor but some of the line-initial "▣"s got garbled into tofu -_- -

What symbols do you like I can do find replace?

4 symbols, so maybe base-4 number system
24 "cards" so assume 0-23
Only 1 base-4 number in that range has 3 of the same digit: 111 (21). So □ must be 1.
Only 9 3-digit numbers in that range, and only 1 of them is 1 followed by 2 digits: 100 (16). So ▷ must be 0.
Digits 2 & 3 will have to wait until I get home. -

I gave you some ASCII for extra safety.

Well I feel that there is a logic to:
▷
□
■
▣But, beyond the triangle I think you can reorder the other three.

@futurebird oh wow this feels way easier
sorting into 3 groups by length, then sorting by first glyph in each... -

@futurebird @apophis ah i would have reversed the two last ones. But that wouldn't make a difference, would it?

@golgaloth @futurebird I hate it when the file stage1.txt is followed by stage10.txt instead of stage2.txt, but it happens
-
@futurebird oh wow this feels way easier
sorting into 3 groups by length, then sorting by first glyph in each...originally had "[" as 3 because i was thinking sloppily and figured "big string = big number" but the error was obvious once i'd sorted the [-initial 3-longs into their sequenced groups of 4 at the end and it was clearly skipping a few series
the -^ order was entirely arbitrary

@futurebird You're connecting it to your digits definitely gave me a lot, I don't know if I'd have had a first thought without it.
▷ : only ever occurs on the right side in "▷", has something to its left otherwise. So numbers go right-to-left and "▷" is 0.
□ : is the only thing that's on the right of a three-symbol sequence. So since there's only one symbol in that position, it's a 1.
That said, I think there are TWO equivent orders. You could have either removed 1 card, or added up to 7 cards, or added 9 to... maybe 38, I think, and made it unambiguous, but what was given was ambiguous:
▷
□▣
■□▷
□□□▣
□■▣▷
▣□▣▣
▣■■▷
■□■▣
■■□▷▷
□▷□□▷▣
□▷■□□▷
□□□□□▣
□□■--
The remaining symbols are "▣" and "■", and they occur entirely symmetrically. So we can use the shapes themselves to judge --
either it goes ▷, □, ▣, ■ -- filling more of the square each time,
or else it goes ▷, □, ■, ▣ -- where □+■=▣ because ▣ is "a filled square ■ in an outline □".

@futurebird ... also tho, are the cards oriented.
Because if □□▣ can alternatively be ▣□□, I haven't tried it out but I'm pretty sure that changes things.

is this alphabetized?

Two cards that could be flipped where the last two the students fit into their pattern.
They decided that having a repeat made no sense.

Il presidente di Confindustria Alto Adriatico Michelangelo Agrusti:
"Credo che, tra le tante cose sbagliate che ha fatto Trump nel suo primo anno di presidenza, questa cosa qui è un fatto che, se avrà successo, potrà cambiare il corso delle relazioni internazionali. Adesso era necessario colpire la testa del serpente, non serviva cercare la pistola fumante come le armi di distruzione di massa a suo tempo per l’Iraq".

L’Italia è un paese talmente fascista che i fascisti vanno in giro per il mondo come ambasciatori a rappresentare l’intera nazione, e quando qualcuno ne chiede la destituzione perché non considera degno di rappresentare la nazione chi ha un passato di militanza attiva neofascista, arriva Marina Sereni del Partito “Democratico” e respinge la richiesta, perché l’Italia è un paese talmente fascista che il Parlamento è diviso tra i fascisti, fiancheggiatori e servi sciocchi.

Draper has a little paper phone book in his wallet.
Reminded me that the most organized I've ever been in my life was when I had a little Sharp pocket organizer that I carried with me all the time. I used it for everything, phone numbers, notes, schedule. It died in a car accident and ever since I never know where I'm supposed to be.
No internet, just storage, 32 kilobytes of it. I should try that again.

di Arnoldo Mosca Mondadori – prefazione di Lettere dei bambini ai fabbricanti di armi
Le novità di cui il mondo ha bisogno nascono nei cuori degli uomini. Nel 1992, Vito Alfieri Fontana era il proprietario di un’impresa che produceva mine antiuomo.
Lo faceva da sedici anni, con ottimi risultati commerciali: aveva venduto in tutto il mondo circa 2,5 milioni di questi ordigni spaventosi, che restano sui campi di battaglia e nei territori sconvolti dalla guerra… https://cctm.website/lettere-dei-bambini-ai-fabbricanti-di-armi/
