Each tile has three lines, of different colours, which go from one side to another. Some sets of tiles can be use as puzzles, in which you have to arrange the tiles so that the edges match in colour, thus forming coloured lines or even loops. There are three kinds of line segments - straights, bends, and corners - and these lead to four different types of Tantrix tile: Three corners 1. 2.

Analyzing Rubik's Cube with GAP
This is an updated GAP 4 version of a GAP 3 example by Martin Schönert, 1993. An almost classical permutation group of small degree is examined with some elementary GAP commands. The output given here has been produced by GAP 4.4, the input is available in form of a plain GAP 4 input file. Ideal Toy Company stated on the package of the original Rubik cube that there were more than three billion possible states the cube could attain. We consider the group of transformations of Rubik's magic cube. +--------------+ | | | 1 2 3 | | | | 4 top 5 | | | | 6 7 8 | | | +--------------+--------------+--------------+--------------+ | | | | | | 9 10 11 | 17 18 19 | 25 26 27 | 33 34 35 | | | | | | | 12 left 13 | 20 front 21 | 28 right 29 | 36 rear 37 | | | | | | | 14 15 16 | 22 23 24 | 30 31 32 | 38 39 40 | | | | | | +--------------+--------------+--------------+--------------+ | | | 41 42 43 | | | | 44 bottom 45 | | | | 46 47 48 | | | +--------------+ First we want to know the size of this group.

Hive at Boardspace.net
Hive is a boardless board game played with Hex tiles. The structure of the game is a fairly traditional chess-like game, overlaid with an insect. theme. The goal of the game is to surround your opponent's queen bee. You can read the details in the official rules, but briefly; the pieces are played but never removed, and must always form one connected "hive". Rules Change: at boardspace the "Queen" opening has been forbidden for both black and white. Robots: Dumbot is a credible but not stellar player.

Rubik's Triamid
This puzzle is a triangular pyramid of 10 odd shaped coloured pieces (actually they are truncated rhombic dodecahedra) which are held together using 4 small cubical connectors. A move consists of pulling off a small pyramid of 4 pieces, and replacing it in any orientation. The pieces have 4 faces (3 adjacent faces of the rhombic dodecahedron) which have one of four colours. For any pair of colours there is a piece with two faces of each colour. In the solved position, Each side of the pyramid has a single colour. If you restrict the moves to those which don't move a corner piece from its place, then this puzzle mimics the Pyraminx. This puzzle was patented by Rubik in Hungary on 28 March 1991 (HU 207,233), and the patent was granted two years later. Number of positions: There are 10 pieces which might be arranged in 10! This leaves 10! Solution: The moves of this puzzle are very hard to describe accurately, and I can think of no good notation for it, so this solution may be hard to follow.

Optimal solutions for Rubik's Cube
A computer graphic of a scrambled Rubik's Cube There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. Move notation[edit] To denote a sequence of moves on the 3×3×3 Rubik's Cube, this article uses "Singmaster notation",[2] which was developed by David Singmaster. Lower bounds[edit] It can be proven by counting arguments that there exist positions needing at least 18 moves to solve. This argument was not improved upon for many years. Upper bounds[edit] The first upper bounds were based on the 'human' algorithms. Perhaps the first concrete value for an upper bound was the 277 moves mentioned by David Singmaster in early 1979. Thistlethwaite's algorithm[edit] Next he prepared tables for each of the right coset spaces . . . . , next to and finally to Intermediate state of the Rubik's Cube in Kociemba's algorithm. Although the whole cube group is very large (~4.3×1019), the right coset spaces and are much smaller. Kociemba's Algorithm[edit] . .

How Gmail destroyed Outlook. - By Farhad Manjoo
As of this week, Gmail has reached perfection: You no longer have to be online to read or write messages. Desktop programs like Microsoft Outlook have always been able to access your old mail. There is a certain bliss to this; if you've got a pile of letters that demand well-composed, delicate responses (say you're explaining to your boss why you ordered that $85,000 rug), unplugging the Internet can be the fastest way to get things done. That's why offline access is a killer feature—it destroys your last remaining reason for suffering through a desktop e-mail program. Google's not alone in providing this option. To get offline access, you first need to download and install a small program called Google Gears (except if you're using Google's Chrome browser, which comes with Gears built in). Now that Gmail has bested the Outlooks of the world, it's a good time to assess the state of desktop software. The shift has been a long time coming.
