20190910 11:41:54 +0200  asked a question  $p$adic extension of $n$th root of unity. I have used the following command to define the 5adic Unramified extension ring in c defined by the polynomial $x^3 + 3x + 3$: Now, I want to find all the $n$th root of unity in this ring for $n$ dividing $124$. I dont know, how the $n$th roots are implemented. Kindly help me with this. Thank you.

20190819 12:05:49 +0200  asked a question  Automorphism group of Coxeter groups Coxeter groups can be invoked using the comment Now, W has three simple reflections S_1, S_2 and S_3. and I am interested in studying the automorphism S_1 > S_3, S_2 > S_2 and S_3 > S_1. Can any one please tell me, how to implement this automorphism of W in sage? Thank you.

20190807 13:54:59 +0200  asked a question  removing the repeated rows of a matrix My sage program outputs a matrix with integer entries in which some rows are repeated. But I want to remove the multiple entries of rows in the output. Kindly somebody explains to me how to do this. Thank you. 
20190807 06:18:41 +0200  asked a question  tree ordering in sage I am using the following code to generate the isomorphism class of trees of order $n$. Then when I print the trees in TreeIterator using loops it is giving the trees in a particular order. Can anyone explain to me what is this predefined order on trees of order $n$ on sage? For n = 6, we have the following order.

I know how to make all the edges labelled. But I need mixed edges (some are labelled and some are not). Kindly help me with this. Thank you 
20181010 08:17:11 +0200  commented answer  creating graph with dotted edges Also in the output graph with dotted edges and ordinary edges, I am getting axes also part of the output. But I need only the graph in order to add it in my paper. Kindly tell me how to get rid of this measurement axes. Thank yu. 
20181010 08:03:52 +0200  commented answer  creating graph with dotted edges Thanks. It works nicely. Can you please tell me how to add labels only on certain edges? thank you. 
20181010 08:02:49 +0200  marked best answer  creating graph with dotted edges Hello all, I need to draw a graph in which some edges are usual and some edges are dotted. I know how to make all the edges dotted (using the option "dotted" for the parameter edge_style of plot). But I need mixed edges (some are dotted and some are usual). Kindly help me with this.
