There are different periodic and fixed points under the iteration of biquadratic sum of digits of positive integer in different carry systems. There are one fixed point, one 3-circle, one 9-circle and one 11-circle in senary; three fixed point, one 9-circle and one 22-circle in novenary; one fixed points, one 3-circle, one 8-circle and one 14-circle in duodecimal system.
