God's Number 20 Trivia Lookup

Bounded game convention/reference only; does not run an omitted strategy or solver.

Description

God's Number 20 Trivia Lookup: look up a supported built-in reference entry.

A move-count bound for a cube depends on how a move is counted. The half-turn and quarter-turn metrics count differently.

This tool returns a built-in reference entry for an exact supported selector. The supported entries and their scope are part of the tool; no website or current external table is queried.

When to use this tool

Use this tool when the supplied inputs match the specific operation described above and you need a repeatable result under its stated convention.

  • Check the supported input and output contract against an existing calculation or observation.
  • Use the complete example to confirm units, selector spelling and result interpretation.

How to use the tool and how it works

  1. Enter every field in the input table using the stated units and the exact supported selector spelling where applicable.
  2. Run the tool. Correct input errors before interpreting an output.
  3. Read the result fields below; use accompanying flags and the stated sign, boundary or model convention when interpreting a number.

Accept 3x3-half-turn-metric and return the stored statement about the 20-face-turn bound.1

Input fieldMeaning and unitsAccepted input
contextContext.Exact value: "3x3-half-turn-metric"
contextBuilt-in entry
"3x3-half-turn-metric"Every reachable standard 3x3 cube state can be solved in at most 20 face turns in the half-turn metric; quarter-turn metric differs.
Output fieldInterpretation
resultObject containing the following named result fields.
result.referenceThe stored entry for the exact selected key; its type may be text, a number or a list.
json
{
  "input": {
    "context": "3x3-half-turn-metric"
  },
  "output": {
    "result": {
      "reference": "Every reachable standard 3x3 cube state can be solved in at most 20 face turns in the half-turn metric; quarter-turn metric differs."
    }
  }
}

Limitations and assumptions

  • The lookup does not solve a cube, validate a state or apply the bound to other puzzles and metrics.
  • Every declared field is required and unexpected fields are rejected. Numeric inputs must be finite; input errors are distinct from a valid false result or an explicitly qualified output.
  • Extremely large inputs and nonfinite or excessively large outputs are rejected. List positions reported by the tool use zero-based indices unless stated otherwise.

Alternative or Complementary methods

Check the underlying observations, units and conventions independently before using the result in a larger workflow. The tools listed below address nearby tasks; compare their inputs and scope before substituting one for this operation.
