A primary pretender for the base *b* is the smallest
composite number *n* for which *b*^{n}
≡ *b* (mod *n*). The list of these (when *b* = 0, 1, 2, ...) begins 4, 4, 341, 6, 4,
4, 6, 6, 4, 4, 6, 10, 4, 4, 14, 6, 4, 4, 6, 6, 4, 4, 6, 22,
4, 4, 9, 6, 4, 4, 6, 6, 4, 4, 6, 9, ... Do you see the
pattern yet? There are only 132 distinct numbers that appear in this
list, but it repeats with a period of length 277#*23#. (Take a moment and calculate how large that period is!) [CGSS1997]
