Comma category with domain formula_65" in. An object of formula_78 is called a "morphism from formula_4 to formula_80" or a "formula_4-costructured arrow with codomain formula_80" in. Another special case occurs when both formula_4 and formula_5 are functors with domain 1. If formula_85 and formula_86, then the comma category formula_6, written formula_88, is the discrete category whose objects are morphisms from formula_8 to formula_10. An inserter category is a (non-full) subcategory of the comma category where formula_91 and formula_92 are required. The comma category can also be seen as the inserter of formula_93 and formula_94, where formula_95 and formula_96 are the two projection
