I have been trying to find out some information on the meanings of the Greek letters. If there is anyone who can offer me some information I'd appreciate it. Thanks.

Do you mean their mathematical values?

If they have any meanings other than Mathematic I'd like to know those as well. I'm supposed to get meanings (i.e. Alpha means beginning, etc.) but the only meanings that I've actually found are mathematical.

These are not meanings *of* the letters, but symbolisms applied *on* and *through* the letters. There are many of them, like ΙΧΘΥΣ (ΙΗΣΟΥΣ ΧΡΙΣΤΟΣ ΘΕΟΥ ΥΙΟΣ ΣΩΤΗΡ = Jesus Christ Son of God, Saviour).

Could you send me a list of those symbolisms for the entire greek alphabet? I am needing that information desperately.

I don't know if anyone can provide you such a catalogue. There are too many symbolisms of that kind, and I haven't seen even an attempt for a list.
