Looking at
http://doc.sagemath.org/html/en/reference/categories/sage/categories/monoids.html
I have not found anything about how to define a finite monoid by simply providing its (binary) "multiplication" table.
Is there some way to do so?

I am completely new to Sage. To test the visualization of a subgroup of SL(2)a, I entered the following code:
G=SL(2,ZZ)
identity = matrix(ZZ, [[1,0], [0,1]])
G.cayley_table(names='elements',elements=[identity, -identity])
which outputs
* [1 0]
[0 1] [-1 0]
[ 0 -1]
+--------------------------------
[1 0]
[0 1]| [1 0]
[0 1] [-1 0]
[ 0 -1]
[-1 0]
[ 0 -1]| [-1 0]
[ 0 -1] [1 0]
[0 1]
Am I missing something to get a correctly displayed result ?
