How many dot patterns is the Braille system composed of?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Braille System**: The Braille system is a tactile writing system used by visually impaired individuals. It consists of raised dots that can be felt by touch.

2. **Structure of Braille Characters**: Each Braille character is made up of a grid of dots. The standard Braille cell consists of 6 dots arranged in two vertical columns of three dots each.
