Take this into TTG: F(A,B,C,D,E,F,G) = Z'm(18,19,21,22,24,25,28,31,40,44,45,58,59,62,63,66,67,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,86,87,88,89,92,93,96,97,100,101,114,115,118,119,120,121,124,125) and when you take it out in the GTT it will be incorrect.

it has to do with the prime implicant table and how you select the proper answers.

V1.7.1 fixed this major bug, as far as i can tell the outputs are correct now. To learn about how i found this bug refer to this separate journey: 2BitALU TruthTable.docx

I guess i should also add that i don't actually know if the results are still minimal!, i tried to make it happen, but depending on how many inputs would have been missing before this change, i am assuming it might be off. haven't quite tested it that far yet though, so if you find anything, make Shure to speak up!
