The number 737 is a numeric symbol used by Public Enemy Number 1 (PENI), a California-based white supremacist gang present on California's streets and in its prisons. The numbers 737 correspond to the letters P, D, and S on a telephone keypad; the initials PDS stand for Peni Death Squad, another name for the group.
Racist skinheads view anti-racist skinheads (typically known as SHARPs, an acronym for Skin Heads Against Racial Prejudice) as enemies and frequently attack them (and vice versa). Racist skinheads also commonly create anti-SHARP imagery that typically demeans SHARPs or implies violence should be used against them.
The Arrow Cross symbol derives from the Hungarian fascist political party known as the Arrow Cross Party that was active during 1935-45. Since then, various neo-Nazis and white supremacists have used the symbol themselves, either generically or as part of the logo of a specific hate group.
