6 bit characters were used by CDC 24 bit machines. 4 chars per 24 bit word.
Lots of companies created 6 bit character sets, all different.
For extra fun take a look at 6-bit (punched tape) codes used for typesetting machines.
They include shift codes (for shifting between Roman and Italic), upper and lower case
letters, all manner of interesting punctuation marks, and more. There too you're
likely to find a different code set for any given manufacturer, and possibly changing from
one machine model to the next.
