   Format: MarkdownItexRegarding the sentence on the terminology "strongly graded": I have moved it from "Properties" to "Definition" (now [here](https://ncatlab.org/nlab/show/graded+algebra#StronglyGraded)) I have hyperlinked technical terms (notably *[[epimorphism]]*) I have added link from the text to the reference (to give readers a chance to see that there is such a reference). In the process, I added the actual definition number. <a href="https://ncatlab.org/nlab/revision/diff/graded+algebra/12">diff</a>, <a href="https://ncatlab.org/nlab/revision/graded+algebra/12">v12</a>, <a href="https://ncatlab.org/nlab/show/graded+algebra">current</a>

   Regarding the sentence on the terminology “strongly graded”:

   I have moved it from “Properties” to “Definition” (now here)

   I have hyperlinked technical terms (notably epimorphism)

   I have added link from the text to the reference (to give readers a chance to see that there is such a reference).

   In the process, I added the actual definition number.
