Hello Doves,I saw the 9 being some kind of key as well.
Just playing around more with 234. I thought about the simple method of marking numbers in base 5(?). Example in the cartoons about someone stranded on an island and they mark off the days with 1 11 111 1111 and four 1111 with a diagonal slash / through it for the number five, and then start over.
Since 2 3 4 are arabic numerals they could be simply represented this way,
2 is 11
3 is 111
4 is 1111 which looks like our arabic numerals 11, 111, and 1111, or the digital clock numbers of 1:11, and 11:11.PK
