J'ai constitué le fichier pieces en suivant les instructions en français du site, mais les instructions en anglais disent le contraire :
3) Edges are numbered in the order used to number the pieces and print the puzzle sheets. If referencing the chart in the UK (and possibly other countries) instruction book (downloadable from http://uk.eternityii.com/about-eternity2/download/), going across the top half, then across the bottom half, for four rows, except for the two extra pieces in the bottom half which are numbered last. i.e.

1 2 3
6 7 8
11 12 13
16 17 18
-------+--
4 5 |21
9 10 |22
14 15 |
19 20 |

For example, the four pieces used in the online demo are:
1 = orange with a cyan (light blue) curved cross,
2 = blue (dark) with a yellow flower looking design (with a centre circle cut out),
6 = magenta (pink) with a yellow cross with bulbs at the end,
7 = purple with a cyan dagger shaped cross.

4) Starting from piece #1, record the number (from the above chart) corresponding to the pattern on the bottom (south), left (west), top (north), and then right (east) edges; in other words clockwise starting from the bottom. Remember 0 is used for a grey border edge.

Alors que le site en français dit qu'il faut numéroter les motifs de 1 à 22 de haut en bas et ensuite numéroter chaque motif sur les pièces en commençant par le haut puis la droite !!

Quelle version est la bonne ?
