## Packing in power...

Given a graph G say and a positive integer k

I am in look out how to remove

edge-disjoint copies of G in G^k

That is edge disjoint copies of G into its power graph all possible ways

Again it is the maximum number of copies I means

Keeping this particular way can someone help kind help please

I will surely acknowledge it

G into to GraphPower(G,k)

## Extract subgraphs from a supergraph...

Problem 1)   Give graph G1 and a graph G2  the problem is to extract maximum isomorphic copies of G1 from G2 such that it has no edge intersection maximum number is floor((number of edges of G2)/(number of edges of G1)) and display the Edge sets of those isomorphic graphs and the graph formed by the remaining edges sometimes their may be no remaing edges too.  Need all possible such copies.

Problem 2) Give graph G1 and a graph G2  the problem is to extract maximum isomorphic copies of G1 from G2 such that each copy has  exactly one edge intersection with each of the copies and that one edge intersection occurs only between those two copies and  display the Edge sets of those isomorphic graphs . Need all possible such copies.

I had written this c++ code years back for problem 2 which i have forgotten kind help if possible to make it better with maplesoft.

Please take your time. Kind help help plese it will be very helpful it is of real help.

Need to maintain memory space as graph size is a little big may be

would usage of database or any other be useful dont know I had done those code in c++ long back which i forgotten logic too.

I would surely acknowledge for this great work as much as I can much more than I can acknowlege too

I am using Maple 2020

How can I write the results inside the Maple code as in the picture? That is, writing the results in terms of gamma and alpha

## Common legend for different figures...

Hello,

Is it possible to have a common legend for different figures? I can plot them as Array of Plots (below) but then they each have a legend.

Is it possible to have the two figures side by side and a common legend in the middle?

Thank you!

restart:
with(plots):
A := Array(1 .. 2):
A[1] := plot([2*sin(x), 3*sin(x)], x = -Pi .. Pi, labels = [x, b*sin(x)], color = [blue, red], legend = ["Case of b=2", "Case of b=3"]):
A[2] := plot([2*cos(x), 3*cos(x)], x = -Pi .. Pi, labels = [x, b*cos(x)], color = [blue, red], legend = ["Case of b=2", "Case of b=3"]):
display(A);

## error, null fix?...

Hi

Keep getting "Error, null" on every calculation i make. It indicates hidden spaces or something weird????.

Screenshot of it is included.

Would be great with a fix or some help because this is driving me mad....

When trying to print a Maple Document as a PDF on Mac, I am now getting an "Error while printing" message. A 1-page pdf is created that's empty.   This is a new error, one that I've never seen when printing as PDF for any other Maple Document I've created.

I'm running Mac OS 12.3.1, the latest version of Mac OS and using Maple 2020.

## Convolution using FFT...

Hi

My integrals are convolutions.and I know I can evaluate this using numerical integration, but I am seeking a numerical solution of this problem using FFT. I have many many integrals of this type to evaluate and I need FFT for speed reasons.

## Signing in to Maple...

Every time I open Maple it has the invitation to Login in the top right-hand corner.  I would like to sign in but have had quite a bit of trouble doing that.  I have a user name and password with Maplesoft web store and the same for MaplePrimes.  Should either of these work to log in?

## How can Maple display an accurate uniform tiling o...

This worksheet creates geodesics in the Poincare disk by transformation of a series of circles of diminishing radii in the complex plane.

The intersections of the geodesics are meant to create the first few pentagonal uniform tilings in the Poincare disk.

I do not know the mathematically correct way to create such a display, so the radii of the circles are only a trial and error approximation.

What Maple code will provide the radii of the complex circles which produce an accurate uniform pentagonal tiling?

Is there a better overall strategy for producing uniform tilings of the Poincare disk?

## Can an ellipsoid be internally tangent to any tetr...

This worksheet displays an ellipsoid internally tangent to the four sides of a tetrahedron.

The tetrahedron is a special case: it has a horizontal base with vertices A,B and C and its fourth vertex E is on the z axis.

However I have failed when trying to display an internally tangent ellipsoid in any other tetrahedron.

Will any tetrahedron support one or more internally tangent ellipsoids?

If so, are there conditions restricting the location of the mutual points of tangency?

Why is the minus sign so weak even in the bold font case? My students sometimes miss it in online tests.
How do we make the minus sign bolder?
Thank you!
