  • Often employed in proof environments to indicate logical progression or steps
  • Useful in creating custom itemized lists or navigation elements
  • Frequently appears in theoretical computer science and mathematical logic for denoting relationships or transitions
  • Provides visual hierarchy in complex mathematical or technical documentation
