In combinatorial game theory, the Sprague–Grundy theorem states that every impartial game under the normal play convention is equivalent to a one-heap game of nim, or to an infinite generalization of nim. It can therefore be represented as a natural number, the size of the heap in its equivalent game of nim, as an ordinal number in the infinite…
The analysis highlights Art, Development and Second Lemma as prominent areas in the source structure around Sprague–Grundy theorem.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.

| checkers is not impartial because | instance of | a game | 0.80 | text |
| supposing Alice were playing red | instance of | a game | 0.80 | text |
| Bob were playing black | instance of | a game | 0.80 | text |
| for any given arrangement of pieces on the board | instance of | a game | 0.80 | text |
| if it were Alice's turn | instance of | a game | 0.80 | text |
| she would only be allowed to move the red pieces | instance of | a game | 0.80 | text |
| and if it were Bob's turn | instance of | a game | 0.80 | text |

The concept neighborhoods around Sprague–Grundy theorem bring nearby vocabulary together. In this analysis, examples include Theorem, Grundy and Sprague. Use the clusters to find adjacent concepts and terminology that may deserve separate research.
For Sprague–Grundy theorem, one of the stronger structural bridges in this analysis connects Sprague–Grundy theorem with Overview. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
TTTA analyzes the structure around Sprague–Grundy theorem to surface related topics, entities, relationships, concept neighborhoods and bridge connections. Use the map to explore areas such as Art, Development & Second Lemma, including less central topics that may reveal useful research gaps. Automatically extracted connections are research leads rather than rewritten encyclopedia content.
