**Triangle Partitions**

This is my contribution to the discussion about triangle partition at Ed Pegg's pages www.mathpuzzle.com

**New problem:** To find partitions, such that no pair of triangles forms a
quadrangle - NON4 partitions

NON4 partitions | ||

4 | 1 | 0 |

5 | 0 | 0 |

6 | 2 | 0 |

7 | 0 | 4 |

8 | 0 | 0 |
