   Format: MarkdownItexI thought it would be useful to supplement the entry _[[operad]]_ with entries _[[symmetric operad]]_ and _[[planar operad]]_, that amplify a bit more on the specifics of these respective flavors of the general notion, and that will allow us in other entries to link specifically to one of the two notions, when the choice is to be made explicit. So far I have written (only) an Idea-section at _[[symmetric operad]]_ with some comments. To be expanded.
