You should have said. Since you quoted the PEP, I inferred you were 
agreeing with the PEP's suggestion:

    even to use a "t" for "ocTal" and an "n" for "biNary" to
    go along with the "x" for "heXadecimal".

Note the "go along with". The X of hexadecimal, and the N of binary, are 
the *last* letter of a syllable, not the first, so I didn't think that 
"first letter of a syllable" was the rule you were applying. If it were, 
you would have picked "C" for oc-tal, not t.

So I guess the rule is:

    "first letter of the word, if the word starts with
    B, or the last letter of the first syllable, if the
    syllable ends with X, or first letter of the second
    syllable if it starts with C, or some random letter
    so long as its not O"

:-)
