For my reference:
Typographical devices such as the asterisk (*) or dagger (†) may also be used to point to notes; the traditional order of these symbols in English is *, †, ‡, §, ‖, ¶.[1] Other symbols, including the #, Δ, ◊, ↓, and ☞, have also been used.[2][3]

The most common sequence of footnote reference marks is:
- asterisk (*),
- dagger (†),
- double dagger (††),
- paragraph symbol (¶),
- section mark (§),
- parallel rules (||),
- number sign (#).
If more are required, they can be doubled up:
- double asterisks (**),
- double single daggers (††),
- double double daggers (††††),
- etc.
However, when many footnotes are used, it is more practical to use consecutive numbers to identify each footnote.
