88 (number)
As a Neo-Nazi symbol
Neo-Nazis use the number 88 as a code to represent the slogan Heil Hitler.[3] The letter H is eighth in the alphabet, so 88 is meant to stand for HH.....
....Examples of usage include: the song "88 rock'n'roll band" by the neo-Nazi band Landser, and the names of the groups Column 88, Unit 88, White Legion 88 and Barselc88. Holocaust museum shooter James von Brunn often signed his writings as "JVB-88."
