In our Reptand prime family, as you know, everybody has our own signature Cycle length. My younger sibling unit has shorter cyclic period and he wanted to create little puzzle for you.
He truncated his cyclelength to five digits. He says if you place 1 at the end of truncated unit, it becomes 3 times larger than if you placed at the beginning of the unit.
What are his signature cycle digits?. He says you don’t have to know him at all to do it.
Show how you deduced it without knowing him?
