I been given a task to decode this and I know it is not morse but cannot find out what kind of code it is. Any help would very much appreciated. Many thanks in advance.
Think of the ○ as 0 and the ● as 1.
Your set lists out the possible ways of arranging them, although it seems incomplete as it misses out 0000 and 1111.
Or maybe my eyes deceived me and they aren't grouped in fours
Maybe my debruin sequence idea was a RedHerring. They seem to be grouped in pars. Maybe it's a binary code (translates to 0,3, 1,2,3, 2,2,1 etc in base 10)
The code is braille. There were 6 lines of braille mixed up through the puzzle. The braille needs to be put together in lines of 2 dots and along and 3 deep and then translated.
