toH

Toh is a term that can refer to more than one concept, and there is no single, universally established meaning. The most widely recognized use of the acronym TOH is Tower of Hanoi, a classic mathematical puzzle created by Édouard Lucas in 1883. In the puzzle, a stack of disks sits on one peg and must be moved to a target peg under rules: only one disk may be moved at a time, a larger disk may not be placed on top of a smaller disk, and the number of moves is minimized. The standard solution employs recursion: move n−1 disks to a spare peg, move the largest disk to the destination peg, then move the n−1 disks onto it. Tower of Hanoi is a staple example in the study of recursion and algorithm design, with many variants and extensions explored in mathematics and computer science.

Outside of Tower of Hanoi, TOH can appear as an acronym in various domains, where the intended meaning depends on context. There is no universally standardized expansion, so the interpretation of TOH should be inferred from surrounding information. In addition, “toh” may occur as part of proper names or transliterations in some languages, but as a standalone term it does not carry a fixed, widely recognized definition.
