Right-Shift Solution: \(102564 \times 4 = 410256\) (The 4 moves from the
back to the front).
Left-Shift Solution: \(142857 \times 3 = 428571\) (The 1 moves from the
front to the back).
Theres no example of Left-shift and x4 ?
No, it is mathematically impossible to have a left-shift parasitic
number with a multiplier of 4 in the base-10 number system.
Why is it called parasitic?
The name "parasitic number" is a piece of colorful recreational
mathematics jargon coined by the popular science and math author
Clifford A. Pickover in his 2000 book, Wonders of Numbers.
Other names:
Dyson Numbers: Named after physicist Freeman Dyson, who famously
posed finding these numbers as a challenge puzzle to the public.
Cyclic Shift Invariants: The formal algebraic term used by mathematicians, as the number undergoes a strict "right circular shift"
during multiplication.
