Hi,

I have noticed that there are some symbols that are used in Modern (abstract) Algebra, that aren't necessarily listed in the math reference. "oplus", indicating a direct product between 2 groups, is one such example. I would like to track down a few others.

My most pressing need, is the sign for "is isomorphic to". (a tilde above an equal sign) How do I make this?

Please help.

I didn't find the right solution from the Internet.
