Illustration of Dipper Relation
When the stars of the Big Dipper are numbered as shown, the sequence:
- $1, 1 +_{3, 4} 1, 1 +_{3, 4} 1 +_{3, 4} 1, \ldots$
traces out those stars in the order:
- first the handle: $\text{Alkaid}, \text{Mizar}, \text{Alioth}$
then:
- round the pan indefinitely: $\text{Megrez}, \text{Dubhe}, \text{Merak}, \text{Phecda}, \text{Megrez}, \ldots$
Hence $x \mathrel {\RR_{m, n} } y$ can be interpreted as:
- Start at $\text{Alkaid}$ and count $x$ stars along the handle and then clockwise round the pan.
- Then start at $\text{Alkaid}$ again and count $y$ stars along the handle and then clockwise round the pan.
- $x \mathrel {\RR_{m, n} } y$ if and only if you end up at the same star.
