The graphic is incorrect... the top group of numbers should have a 2 instead of a 0 as the first digit of the second row, and the second group of numbers should have a 3 instead of a 1 as the first digit of the second row

What about the third group? Shoudln't the 2nd digit on the 2nd line be a 4?
And the fourth group. Shouldn't the 2nd digit on the 2nd line be a 5?

How difficult is it to count by 4s? Quite difficult, I guess! :-)

I'm assuming the first digits in each row are correct. I don't know. Can the originator please straighten this out for us?

Are there any more?
