I am aware of two ways in which “770” is symbolic. Both ways are religious (but of different religions). One is relatively easier to guess. The second is a bit obscure.
The award for guessing any one of them is, um, my eternal awe.
WRS - 770!
(If the winner is/winners are religious-minded, I can pray for him/her/them for two weeks (7 days, 7 days, and 0 days).)

If you worship at the altar of UNIX, then you’ll recall that the octal code 770 can be used as an argument of chmod to assign a file read, write, and execute permissions for owner and group only – others have no access to the file.
Bingo! You got it. 770 East Parkway, Brooklyn, NY was/is the headquarters of Lubavitcher Chassidism. It was, if I remmeber correctlyl, where the Rebbe lived.
Prayers for astro and ParentalAdvisory!
Now the second meaning? Quite obscure, I’ll admit. So, if no one gets it in five days, I’ll reveal it.
