Jarrett notation 
is an alternate
notation to the modern 
for the factorial. It was introduced by Jarrett (1830,
1831) and for a time commonly used in the United States and Great Britain (Cajori
1993; cf. Mellin 1909; Hall and Knight 1950; Lewin 1958, p. 19; Dudeney 1970;
Gardner 1978; Conway and Guy 1996).
