Re: I can't login to my username, created the same username again?

Perhaps you registered as marksquall and later renamed your account to what it is called now?

Re: I can't login to my username, created the same username again?

When I look up the account marksquall there are no solved problems, and the user ID is 1441140.
What user ID does your marksquall account have?

Perhaps you don't remember the (previous) username correctly.

It's the way it is intended.
If you go to the main statistics page and switch to "view data for active members only" you can view the active Python members.

Could you try another browser?
With me the problem turns up in IE11, but not in Chrome or Firefox. (With seemingly random pages. By me the page affected behaved normal again after about 48 hours)
Please let us know the result.

Re: I do not know/remember my Recovery Key

You generated your recovery key on Sat, 25 Mar 2017, 23:56.30.
The only way to recover your account is to find back this key. I assume that you saved it somewhere.
If you don't find it back, your account is lost.

Squaring a matrix has nothing to do with matrix addition.
What you can read there is that for some matrices A,B,C holds that $A=B^2$ but also $A=C^2$

Re: Problem 038

If you want to go up to 5 you have to concatenate 2469*1 and 2469*2 and 2469*3 and 2469*4 and 2469*5.
This gives 246949387407987612345

The alternative account could have been creyD_
That one has solved one more problem than creyD has solved now. The problems solved by creyD were also solved by creyD_.
