These are questions asked by Matt C Anderson

Hi MaplePrimes,

I have decided to look for an odd perfect number.  
I want Maple code to determine if there is a perfect number beween bounds on a factor.
For definitions of deficient and perfect and abundant numbers, see
https://mathworld.wolfram.com/DeficientNumber.html
https://mathworld.wolfram.com/PerfectNumber.html
https://mathworld.wolfram.com/AbundantNumber.html

I need some sort of loop that closes in on the edge of abundant/deficient numbers.

Specifically, an IF() statement is needed about wheather the function

sigma(a)-2*a is positive or negative.

Regards,

Matt

Simple question

Got stuck

tup_10_g_trying.mw

Want output to look like - 

tuple10(50,12,14,0,0,0,0,0,0,0,0)

1 5 17 19
2 17 29 31
3 29 41 43
4 47 59 61

Please assist.

Hi again everybody,
I hope this can help in some classrooms.

This procedure has some warnings.  Someone else can clean it up.
Also, the ithprime() command can make it a bit slicker.
I did work with prime constelations project, and you can see my web page at mattanderson.fun  .

Refference oeis.org/A40 .
Some prime constelations, and k-tuples, are not of 'general intrest' yet, so they are not in the OEIS encyclopedia YET!

But prime numbers are exciting.  I like doing calculations.

Hopefully someone in the next generation will take up an intrest and do what I did.

I wish the best on all of you.

Thank you very much, Maple Community !

I have another (hopefully) easy question about a data set

seematrix_start_2_trim.xlsx

matrix_start_2_trim.pdf

I want to imitate Online Encyclopedia of Integer Sequences .b file

reference oeis.ort/A40

Cheers,

Hi again,

Are there any Maple experts out there that can help me save a matrix full of data?
