In section 5.2.1.21 author talks about graph-indexing category(GrIn) and symmetric graph-indexing category(SGrIn).
Ex. 5.2.1.26 asks
How many functors are there of the form GrIn → SGrIn?
I did not understand the answer and explanation given in the textbook. Can anyone please explain ?
This was the question I mentioned in the meeting. Part a is what I was trying to figure out.
