First Claim
1. Machine-readable coded data disposed on or in a substrate, the coded data including a plurality of layouts, each layout having n identical sub-layouts rotated 1/n revolutions apart about a center of rotation, where n is at least two, each layout encoding:
- a first codeword comprising a sequence of n first symbols, each sub-layout defining a position for a respective first symbol, the first symbol being indicative of the identity of the sub-layout;
a second codeword comprising a number of second symbols, the second codeword being indicative of information regarding the respective layout; and

Abstract
Machine-readable coded data disposed on or in a substrate. The coded data includes a plurality of layouts of two or more layout types, each layout having n identical sub-layouts rotated 1/n revolutions apart about a center of rotation. Each layout encodes a first codeword formed from a sequence of n first symbols, each sub-layout defining a position for a respective first symbol so that the first symbol indicates the identity of the sub-layout. The layout also encodes a second codeword formed from a number of second symbols, which indicative of information regarding the respective layout and a number of third symbols which are partially indicative of a third codeword.
