How about sixteenths?
Cis-Atlantic music notation is bedevilled with medieval note-value names
called quavers and crotchets and demisemiquavers. The Germans brought to
America a simple system that calls notes whole notes, half, quarter etc.
I frequently refer to n-tiles as quarters, fifths and tenths. The system is
extensible. And, indeed, generating too many quantiles from a small dataset
produces fewtiles.
Incidentally, what happens if you divide your data into three groups based
on rank, send them down the New York drains and teach them martial arts?
