Most of the solutions just output the solution in a format similar to ours, except sometimes only the four visible sides are shown, so I visually compared one of their outputs to mine directly, and guessed the rest of the solutions they find would match as well. This table form is handy.

To compare with the output of tye's script, we convert each solution to the format of his output. We can't use just the normalized solution because tye's script normalizes in a different way.

Indeed, output for index 4 is equal to tye's output.

I've checked the output of most solutions in this thread, and each seems to give at least one correct solution, or at most sneaked in so typos so smartly that I didn't notice them in my not too rigorous comparision. I don't yet understand the output of solutions in L~R's second order reply.
