# WHY?
# Since any found solution has an inverse we want to maximize finding solutions that are not already found
# as an inverse. The inverse will ALWAYS be 3 one of the piece configurations that is exactly 3 rotations away
# (an odd number). Checking even vs odd then produces a higher probability of finding more pieces earlier
# in the cycle. We still need to keep checking all the permutations, but our probability of finding one will
# diminsh over time. Since we are TOLD how many to search for this lets us exit before checking all pieces
