> "420*(3*19+27)/2*27=476280 moves at least."In my calculation there are only 20 "shots" needed to
move blocks in line 16. Thus my estimate is a bit less:
#moves between
(6+42*20+2)*420 = 356,160
and
(6+42*20+2)*420+420 = 356,580
Does anyone have an idea why "eag" used a factor 27?
Anyway, even this number is amazing.
I had to change my vote for the poll,too ;) (msg #5227)
As I see, the 6 "rooms" in lines 1-6 can be flipped
thus making a loop of 6 extra moves. Two shots will
then cost 420+11*6=486 moves, making a total of
412,128 moves.
