Subject: Query: Code?

Hello,

I am currently researching a documentary about a murder in New Zealand.

The killer contacted police and left the number 12640 which may be a
code of some sort.

Can you recommend an online messageboard where I could ask
mathematicians to comment on the number?

Many thanks,

Cinna Smith
