You can BFF but not LOL in hex

kw: observations, musings, wordplay

I happened to notice recently that the abbreviation BFF (best friends forever) showed up as part of one of those long URL's that contain strings of hex-codes. In case anyone is interested, the hexadecimal string BFF converts to decimal 3071.

I ran an exclusion search of my spelling dictionary and found 66 words formed only of the letters A through F:

A
AB
ABACA
ABBE
ABE
ABED
ACCEDE
ACCEDED
ACE
ACED
AD

ADE
BAA

BABE

E
EBB
EBBED
ED
EFFACE
EFFACED
FA
FACADE
FACADED
FACE
FACED
FAD
FADE
FADED
FED
FEE
FEED

Just a few of these require explanation: E is found in the Latin motto "E Pluribus Unum" on the dollar bill, and means "from"; ABACA and ABBE are names; and FA is the tone-name of the fourth musical note in the diatonic scale (Do-Re-Mi-Fa-Sol-La-Ti-Do). The others all ought to be well known, though the adjective FACADED is getting obsolete.
