@amWhy Answer now deleted by its author, with the effect that the comments thread becomes invisible to many.

@JackDAurizio Why did you delete your answer mentioned just above? Is it due to some problems in the mathematics that you discovered afterwards, or is it to make the thread of comments less visible? If the latter, whatever one thinks of the facts/opinions/judgements/anything that were voiced there (your own included), I find suboptimal to make them disappear.

This question is being asked. Again.

The new version doesn't seem any clearer than the old version...

Ugh... I was just told by a review audit that this PSQ was a perfectly good question, and that I shouldn't have voted to close. :\

Sigh...

close votes needed here. It's a copy and paste graded homework or test into post, beg for help question.

...and the linked post immediately above even just earned an upvote.

This can be closed. Doesn't seem the OP is coming back to save their post.

@JohnMa It's now open for deletion.

It's been a long day... I believe this question needs to be closed. Too many Sunday-before-homework-is-due/exam-on-Monday questions today (no surprise, but tiring). @ProfessorVector, @XanderHenderson, @JohnMa @Did, @user21820

$\mathbb{Z}_p$ is NOT unambiguous notation! Come on, peoples!

This is a duplicate of this. I used up my close votes until 40 minutes from now. Will vote to close at dupe then, but hoping for a head start!

Oh, snap. I'm out of votes. :\

25 minutes to go, dear @XanderHenderson counting down, you can join me!.
