• 16:3316:33, 30 January 2022 diff hist +13 m Category of manifolds Made the notation consistent with pointed space by adding the curly braces { and } around the single point, to denote the single point set.

• 20:0420:04, 29 January 2022 diff hist +121 m Pointed set Making <math>\mathbf{1}</math> explicitly selecting a singleton set, according to the definition. So that morphisms from the image of <math>\mathbf{1}</math> itself also selects an element in the image of the morphisms.
• 18:4318:43, 29 January 2022 diff hist −4 Pointed space Replaced "such morphism" with "such maps" because it refers to the preceding continuous maps. Keeping "morphism" creates confusion with the following mention of "morphisms".
