For the 68s, the card counts (ebay listings) of the Tracewski, Stephenson, and F Robby (500) are much higher than the counts for the May, Bryan, Von Hoff, & Robby checklist. So, it may be that a 3x4 & 4x3 arrangement was actually used, but that hasn't yet been fully established.

Neither has the 1x5, 1x4, and 5x3 layout IMO
