yeah, no clue where to start. I mean I see a grid, see the letters where numbers should be, see that they're identical discs, but that's all I see.

not sensing a discrete pattern.

seriously, who taught whoever was responsible to write that number that way?

i feel like I have. Come on, home more credit than that...in various forms... the fourth number is messy, is it double digits?

unsure about what to do once I've got the numbers (LCD digits again?)

thanks, I thought it might be that but was not on a situation where I could really do that.

so yeah. This one. It took me a while to get back to the book. It almost looks like spacings for[ a keyboard again, except for the goalposts. I don't feel like I have a starting point/spoiler]

It's easy to recognize the number. It's harder to get that many digits right.
