The official record for the resolution of the cube is 22.95 seconds..
Indeed it is the best time of the world championship 1982 (established by Minh Thai) and it is the reference,
even if the record in official competitions is 17.04 seconds, established by Robert Pergl during the
Czechoslovak Championship of 1983.

Here is the number of accessible positions from a finished Rubik's Cube, and without unsettling it:
(12! x 8! x 2^{12} x 3^{8}) / 12 = 43 252 003 274 489 856 000 (or 4.3 x 10^{19})
To give you an idea: if you owned one Rubik's Cube for every possible position, you could cover the planet Earth not less than 270 times.
The Rubik's Pocket, a 2x2x2 Rubik's Cube, has 3674160 possible positions.
The Rubik's Cube Revenge has
7401196841564901869874093974498574336000000000 (or 7.4x10^{45}) different
There is also a 5x5x5 Rubik's Cube: the Professor's Cube or Ultimate Cube (or also Rubik's Wahn).
The number of positions it can reach is :
282870942277741856536180333107150328293127731985672134721536000000000000000
(or 2.8x10^{74})
In theory the smallest number of movements to solve a Rubik's Cube from any position is 22.
But until now nobody managed to find a method which would effectively allow to do it. This algorithm's name
is "God's Algorithm" but it is not known.
The largest Rubik's Cube was built by Daniel Urlings (Luxemburg). Its edges are 3.52 m [3 yd 2 ft 7 in] long.
The most expensive Rubik's Cube was the Masterpiece Cube, produced by Diamond Cutters International in 1995.
The actualsize, fully functional cube features 22.5 karats of amethyst, 34 karats of rubies, and 34 karats
of emeralds, all set in 18karat gold. It has been valued at about US$ 1.5 mio.
It took one month of intensive practice to Ernö Rubik to solve for the first time its brain teaser.
Before, he wasn't even sure that there was a method to achieve it.
Another interesting number : if you dismantle the Rubik's cube (that is to say separating all the little cubes) and that you
put it back together randomly, there's 11 chance in 12
of not being able to reach the final position. (have a look at the beginning of the Solution section for the explanation)
At least 1 people on 5 already played with a Rubik's Cube.
200 millions : this is the number of cubes that were sold in the whole world until now
(without counting the Asian imitations), according to the manufacturer.
