The package is tested against Julia >= 1.6.0 on Linux, macOS, and Windows64.

Very early in the development cycle.

## Julia implementations of integer triangles.

We give a framework for computing mathematical integer triangles and use it to create so called "Integer Triangle Trait Cards".

A trait card is a compilation of the essential characteristics of an integer triangle, whereby we understand the characteristics of a triangle to be integer sequences that can be obtained from the triangle by elementary transformations.

To see what you can expect start by executing

```
using IntegerTriangles
TraitCard(BinomialTriangle, 8)
```

Overview tables can be automatically generated for a variety of triangles and traits.

A-Number | Triangle | Form | Function | Sequence |
---|---|---|---|---|

A000302 | Binomial | Std | PolyVal3 | 1, 4, 16, 64, 256, 1024, 4096, 16384 |

A001333 | SchroederB | Inv | AltSum | 1, -1, 3, -7, 17, -41, 99, -239 |

A006012 | SchroederL | Inv | AltSum | 1, -2, 6, -20, 68, -232, 792, -2704 |

A026302 | Motzkin | Rev | Central | 1, 2, 9, 44, 230, 1242, 6853, 38376 |

A103194 | Laguerre | Std | TransNat0 | 0, 1, 6, 39, 292, 2505, 24306, 263431 |

nothing | Laguerre | Rev | TransNat1 | 1, 3, 15, 97, 753, 6771, 68983, 783945 |

Important: Note that we assume all sequences to start at offset = 0. Also note that all references to A-numbers are approximativ only, i.e. the first few terms of the sequence may differ and the OEIS-'offset' is always disregarded.

To use this feature you have to download the file stripped.gz from oeis.org, expand it and put it in the directory ../data.

You can also look at the demo notebook.
