# sorted order. Since that array starts on an odd row, the offsets for an odd row are: [0,1,6,11,17] obtained
# by subtracting 8 from everything. Now imagine the piece shifted up and to the right so it's on an even row:

# the reason for it is basically to force a particular ordering on how the rotations are tested for
# the first piece. It is called twice, first looking for placements of the odd rotations and then
# looking for placements of the even locations.
#
# 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
# this bennifit is very great when seeking small numbers of solutions and is 0 when looking for more than the
# maximum number
