Plural tiles are positioned in a plate-like array. The tiles have edge portions that overlap in such a way that no straight-through joints are present between abutting tiles and such that the thickness of the entire array does not substantially exceed the thickness of a single tile. 1. A tile having:{'b': 35', '53', '35', '53', '56', '57', '56', '57', '56', '57', '59, 'a major surface face () bounded by an octagonal edge () at the perimeter of the major surface face (), the edge () consisting of four side edge portions () and four chamfer edge portions (), the side and chamfer edge portions (, ) alternating progressively around the perimeter with each pair of adjacent side and chamfer edge portions (, ) extending from a corner () at an internal angle of 135° relative to each other;'}{'b': 10', '28', '10', '28', '56', '35', '10', '30', '10', '35', '10', '10', '35', '10', '10', '35', '10', '65', '70', '56', '35', '10', '56', '35', '10', '59', '35', '30', '10', '10', '10, 'sub': 1', '2, 'a minor surface face () that is bounded by a rectangular edge () at the perimeter of the minor surface face (), the edge () consisting of four edge portions that respectively extend in parallel to the four side edge portions () of the major surface face () when the tile is viewed facing normal to the minor surface face () with each pair of adjacent edge portions extending from a corner () at an internal angle of 90° relative to each other and, the minor surface face () having a smaller area than the major surface face (), the minor surface face () being positioned such that the perimeter of the minor surface face () does not extend outwardly of the perimeter of the major surface face () when the tile is viewed facing normal to the minor surface face (), and the distance (D, D) from the minor surface face () perimeter to the major surface face () perimeter being uniform around the perimeter of the minor surface face () where the distance is measured along lines (, ) extending ...
