I am trying to generate a 3-color 20 string pattern. The pattern is about 100 lines long. When I try to save this pattern, it tells me "the dimensions of the pattern are too big. Read more on the generator page on the website"

First question: can someone tell me what the maximum dimensions of a pattern are?
2nd question: where can I read about the generator, which might tell me more about limitations of the generator?

the maximum for normal patterns are 64 threads, and 80 rows. the old generator allowed for longer patterns, but we limited that number in favour of the better, easier to use generator.
