So, you're going to get a value that's a multiple of 4. The probability that the number of cards you're holding is the number you first calculate is 1/4, or 25%.

So: if you're holding x cards, how many times do you have to add or subtract? Let's find out!

1 = 40 - 13*3......14 = 40 - 13*2.......27 = 40 - 13*1..........40 = 40

2 = 28 - 13*2......15 = 28 - 13*1.......28 = 28....................41 = 28 + 13*1

3 = 16 - 13*1......16 = 16................29 = 16 + 13*1..........42 = 16 + 13*2

4 = 4 ................17 = 4 + 13*1.......30 = 4 + 13*2 ...........43 = 4 + 13*3

5 = 44 - 13*3......18 = 44 - 13*2......31 = 44 - 13*1 .......... 44 = 44

6 = 32 - 13*2 .....19 = 32 - 13*1 .....32 = 32 ....................45 = 32 + 13*1

7 = 20 - 13*1 ......20 = 20...............33 = 20 + 13*1 .........46 = 20 + 13*2

8 = 8 .................21 = 8 + 13*1 .....34 = 8 + 13*2 ...........47 = 8 + 13*3

9 = 48 - 13*3 ..... 22 = 48 - 13*2 ....35 = 48 - 13*1 ...........48 = 48

10 = 36 - 13*2 ....23 = 36 - 13*1 ....36 = 36 .....................49 = 36 + 13*1

11 = 24 - 13*1 ....24 = 24 ..............37 = 24 + 13*1 ..........50 = 24 + 13*2

12 = 12 .............25 = 12 + 13*1 ....38 = 12 + 13*2 ..........51 = 12 + 13*3

13 = 0 + 13*1 ....26 = 0 + 13*2 ......39 = 0 + 13*3 ........... 52 = 0 + 13*4

So, if you're holding between 10 and 38 cards, you add or subtract 13 no more than 2 times. If we don't count adding straight thirteens to 0, the upper bound increases from 38 to 42.

I conclude that optimal range is to leave at least 10 cards on the table and pick up at least 10 cards.

So: if you're holding x cards, how many times do you have to add or subtract? Let's find out!

1 = 40 - 13*3......14 = 40 - 13*2.......27 = 40 - 13*1..........40 = 40

2 = 28 - 13*2......15 = 28 - 13*1.......28 = 28....................41 = 28 + 13*1

3 = 16 - 13*1......16 = 16................29 = 16 + 13*1..........42 = 16 + 13*2

4 = 4 ................17 = 4 + 13*1.......30 = 4 + 13*2 ...........43 = 4 + 13*3

5 = 44 - 13*3......18 = 44 - 13*2......31 = 44 - 13*1 .......... 44 = 44

6 = 32 - 13*2 .....19 = 32 - 13*1 .....32 = 32 ....................45 = 32 + 13*1

7 = 20 - 13*1 ......20 = 20...............33 = 20 + 13*1 .........46 = 20 + 13*2

8 = 8 .................21 = 8 + 13*1 .....34 = 8 + 13*2 ...........47 = 8 + 13*3

9 = 48 - 13*3 ..... 22 = 48 - 13*2 ....35 = 48 - 13*1 ...........48 = 48

10 = 36 - 13*2 ....23 = 36 - 13*1 ....36 = 36 .....................49 = 36 + 13*1

11 = 24 - 13*1 ....24 = 24 ..............37 = 24 + 13*1 ..........50 = 24 + 13*2

12 = 12 .............25 = 12 + 13*1 ....38 = 12 + 13*2 ..........51 = 12 + 13*3

13 = 0 + 13*1 ....26 = 0 + 13*2 ......39 = 0 + 13*3 ........... 52 = 0 + 13*4

So, if you're holding between 10 and 38 cards, you add or subtract 13 no more than 2 times. If we don't count adding straight thirteens to 0, the upper bound increases from 38 to 42.

triple negative = single negative lol

My approach was: 136/4 = (100+36)/4 = 25+9 = 34. Average is 34. OK. 31, 33, 35, 37.

For every state of one cube, there is exactly one state of the other cube in this puzzle, are there not? Then this puzzle has just as many states as the original rubik's cube: 12!*8!*3^12*2^8/12. Perhaps I have missed something; if so, enlighten me.

Actually, now I see it's not quite as simple as I had thought. Pay attention to the interaction between the green and blue faces, and you'll see that while one green face turns it does nothing to the blue face on one cube, but something to the blue on the other. Then, if g is a ccw turn of the green face on one cube, and b a ccw turn of the blue face on the same cube, gbgbgbgb will result in one cube being solved but not the other.

This is recent? I saw this the first time I looked at Pascal's triangle... but then, I suppose the proof would take some time to develop.

2 es el más raro porque es el único que es par? bueno, 3 es el único igual a 0 mod 3, 5 el único igual a 0 mod 5.... todos son iguales de raro pensando así :P
