# Strand

A **strand** is a distribution pattern for a single digit in 3 of the 9 intersections aligned in a chute. This term is used in Braid Analysis.

There are 6 different strands in each chute.

## Strands in Floors

Each rectangle represents a boxrow that belongs to the floor. There are 3 cells in each boxrow. For the purpose of determining the strand, the exact position of the digit in that boxrow is ignored, as long as it is placed *somewhere* in that boxrow.

When we ignore wrapping around, each strand follows a diagonal path. Strands that follow a \ direction are identified with the letter **N** and strands in the / direction are identified with the letter **Z**. The number refers to the starting position, which can be **1** (top), **2** (middle) or **3** (bottom).

## Strands in Towers

Each rectangle represents a boxcol that belongs to the tower.

In towers, the strands are numbered from left to right.
