Chess324 is a subset of DFRC, with kings and rooks on their "normal" positions of
classical chess (kings e1/e8, rooks a1,h1/a8,h8). So, in Chess324 no special
chess-rules (castling-moves!) are needed.
DFRC is FischerRandomChess (also known as Chess960) but including non-symmetrical 
positions of the pieces of white and black...

Chess324 64x means: All Chess324 positions combined with 2 single-step pawn-plies
(example 1.a3 c6 or 1.e3 h6 and so on): 64 of these 2 single-step pawn-plies are
possible, so there are 324 * 64 = 20736 possible different openings for evaluating.
These opening-lines were evaluated (endpositions) with KomodoDragon 2.6 (10 seconds 
per endposition on a 12 core AMD Ryzen CPU)

Chess324 xxl means: All Chess324 positions combined with 6 single-step pawn-plies
Example: 1. h3 h6 2. g3 d6 3. d3 b6 
So more than 600000 different Chess324 openings were possible and evaluated!!!
The Chess324 xxl sets are around 30x bigger than the Chess324 64x sets...
