Where's the infinity symbol? What font?

[Guest]

How do I write it in Word?

Thanks,
A perplexed math teacher.

In Word 2002 and 2003, you can type 221E and press Alt+X to
insert a lemniscus or infinity symbol. Or insert symbol number
165 from the Symbol font. If you use this symbol often, then you
could assign it a keyboard shortcut.
