cool idea!#3: Thomas Genuine (Genuine) on Jun 1, 2014
you said 3 color mistakes, and I've found 3 fairly quickly so I'm not going to keep looking....r19,c14 should be white(34-factor of 2 primes). r18,c14 should be green(54-has factor of 9 which is a cube). r18,c15 should be white(55-factor of 2 primes)
thx Kurt!#4: Thomas Genuine (Genuine) on Jun 1, 2014
(Maybe more mistakes?) :)
OK Kurt, originally I meant changing of 54-55 is ONE mistake! :)#5: Cynthia Lynn McDaniel (mcaardva) on Jun 15, 2016
There is another one. Let it to other solvers! :)
My head hurts.#6: Andrew Schultz (blurglecruncheon) on Sep 15, 2019 [HINT] [SPOILER]
I wrote a python script to figure this out.
209 = 11 * 19 and should be white but is listed as blue.
185 = 5 * 37 and should be white but is listed as green.
65 = 5 * 13 and should be white but is listed as blue.
In addition to the 54/55 flip and 34 listed above.
