These two types of partition are in [[bijection|0GG9TVW90M]] with each other, by a diagonal reflection of their Young diagrams. Their numbers can be arranged into a triangle, the **triangle of partition numbers**, in which the $n$th row gives the partition numbers $p_1(n), p_2(n), \\dots, p_n(n)$:\n",
