Manchester coding is a type of encoding system where each data bit is either low then high, or high then low.
This so-called self-clocking signal was widely used...Show more for data recording and is still in use in various systems today.
The basic coding technology inspired our design.
Multiplex requires to pack the four pieces with Manchester encoded edges in the tray.
Out of 12,288 theoretical combinations to try there is only one solution, so solving requires skill to remain unruffled,
For ease of storage and travel, this tray puzzle comes with a lid.
