20160107 10:38:15 0600  commented answer  Introducing a finite monoid by giving its "multiplication" table I guess there is a problem with one line of the current code "assert 0 <= data < len(self._table):". The last symbol of such line must be deleted. 
20160105 04:17:38 0600  commented answer  Introducing a finite monoid by giving its "multiplication" table Thanks a lot. I will check whether this method allows using the issues already implemented for monoids (direct products, quotients, homomomorphisms, etc) without having to code anything else. Indeed, this reason was the motivation behind my question. By the way, do you already know the answer? 
20160104 18:48:00 0600  asked a question  Introducing a finite monoid by giving its "multiplication" table I am interested in working with some finite monoids. Looking at http://doc.sagemath.org/html/en/refer... 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?

20150325 09:13:49 0600  commented answer  3D grid like the one in the picture Thanks, it is exactly what I wanted. Do you know whether it is easy to write numbers (like a kind of labels) to each one of the balls (in such a way that we can later search for the ball with number 1, for the ball with number 2, etc) 
20150325 06:27:02 0600  asked a question  3D grid like the one in the picture I am interested on drawing with Sage something like the following picture The code that appears in the picture uses Wolfram Language (and I got the picture from this link) Moreover, what I am interested is to have some function that creates such a picture from a list of points (where by a point I refer to an element of $\mathbb{Z}^3$). Does anybody know how to do this with Sage?

20140202 21:07:02 0600  commented answer  Nice display of a list of "matrices" Thanks. Is there some easy way to get the output in pdf format (or in png, jpg)? I ask this because later I want to use this output inside a paper I am writing using LaTeX. 
20140131 11:52:36 0600  marked best answer  Nice display of a list of "matrices" You could define a function to produce a latex array (or tabular): and then view it:

20140130 01:04:58 0600  asked a question  Nice display of a list of "matrices" In the context of graphs I have seen that it is possible to display in a very nice picture of all graphs in a certain list using for instance the following code: The output one gets is the picture I would like to get the same output display but this time using a diferent kind of objects (instead of graphs), namely matrices for the sake of this question. So, here is the question: suppose you have a list L of matrices, for example the one defined by Is there some way to obtain a picture of the same kind than before except for replacing the graphs with the display of each one of the matrices in L?

20130419 07:29:48 0600  marked best answer  Showing options after writing "." when you choose an element of a list

20130418 04:15:22 0600  commented answer  Showing options after writing "." when you choose an element of a list Thanks for your answer. Then, I imagine that this should be something to add to the "to do list" for the sage notebook, since in the notebook this would make sense (first evaluate "c[0]" and then show the list of options for this evaluation). Do you think this suggestion makes sense?

20130418 00:16:00 0600  commented answer  Showing options after writing "." when you choose an element of a list So, there is no way to run some sage command that tells that the list c I have just created is a list of graphs (in this particular case)? I guess that if we could do this, then it might be the case that later it works the completion for "c[0]". 
20130417 23:38:14 0600  asked a question  Showing options after writing "." when you choose an element of a list Let me illustrate my question with a particular (naive) example of a list. In this situation if in a new line one writes down "a." and press "Tab", then one gets a list of all options to be used for the object a (for example "a.category", "a.center", etc.). On the other hand, if in a new line one writes down "c[0]." and press "Tab", then one does not get the right feedback. Is there some way to make this work like in the previous paragraph (and display the options for the object "c[0]"?
