Just looking at the other SS:
 * Necessarius - 『必要悪の教会』特別編入試験編
 * Biohacker - バイオハッカー編
 * Agnese - アニェーゼの魔術サイドお仕事体験編

The 編 character is what we've translated as Arc. But all the SS have it; we only translated it for Biohacker for some reason.

EDIT: Just checking all the old links.
 * Toaru Majutsu no Index SS: Biohacker Arc
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 1
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 2
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 3
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 4
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 5
 * Toaru Majutsu no Index SS: Biohacker Arc/Chapter 6

EDIT: Missing redirects added.
