Default Righting a wrong

I've been contributing off-and-on to GIMPS for 13 years, especially over the past couple, but I've never completed a FT LL test. Selfishly wanting to "get one under my belt" before they disappear, I manually reserved 110986373, ran an LL test (obviously composite), and turned it in. I then noticed its P-1 was woefully underdone, so I took 48 GB of RAM and turned it loose on that exponent (no factor).

Now, after some thought, I'm feeling guilty about running an LL test when I know that it's wrong and had the means (I use mprime 30.5) to run a PRP test with GEC and proof. Since it's Good Friday where I am (I'm a lapsed Catholic, but I'll play along), I'm willing to pay the penance of running the PRP "DC" of this exponent. The questions I have are, is it legal (will the system accept it, since I can't reserve it?) and is it ethical (since I'm effectively DCing my own LL test, albeit with a PRP test which will be verified with a proof)?

Yes, it will be accepted, and because it's a different assignment type, PRP instead of LL, the exponent will be closed by certification for good.

That was a sin. You can not earn redemption. As your penance say 5 Hail Marys and do 5 PRP/proof assignments as DC of LL first tests by others from the manual assignments page. "Double check using PRP with proof"

5 Bloody Marys and 5 unblended scotch shots. You are forgiven.

I'll get to the DCs eventually (I only have one good computer, which runs part-time). Rather than say five Hail Marys (which I'm loathe to do as I'm now an atheist), I'll instead rewrite the prayer with a GIMPS theme (hoping nobody else has already done it):

Quote:
Hail Marin, full of grace,
the primes are with thee,
Blessed art thou amongst friars,
and blessed are numbers of thy name, Mersenne.
Holy Marin, Father of GIMPS,
pray for us searchers,
now and at the hour of discovery. Amen.
"Father" in this case is "priest", not "founder", so this is not a slight at George.

I haven't had a drink (communion wine) since I stopped going to church 15 years ago. That would probably cause a lot of issues.

Remember: two wrongs do not make a right.

Three lefts do.

But also 7 lefts, or 11 lefts, or any amount of lefts of the form 4k+3, with k being from the set N0.

A couple other fun cases:
1) westbound at the equator, turn right 90 deg, proceed to 90deg N. Turn right 90 deg. Proceed to equator (90 deg southward). Turn right 90 deg. You're back on the original heading, 90 degrees longitude east of start, after 3 turns of 90 degrees. Two rights made a left.

2) From level westbound flight, yaw right 90 degrees. Pitch up to 90 degree vertical climb (F16 suggested). Before stall yaw right 90 degrees. Yaw right 90 degrees again. You're now cockpit south heading downward (assuming flight path yields negligible latitude and longitude changes, and sufficient altitude remains). Roll right 90 degrees to cockpit westward. Pitch up 90 degrees to original heading and level flight. The SIXTH 90 deg maneuver overall, third yaw right puts you back on a westward course.

One is sufficient when at the dentist. In fact telling him "pain in the lower right k9" with corrections for his point of view would result in the wrong tooth being worked on. Which reminds me of an experiment in college. The whole class were lined up to jump over
a pommel-horse. I asked the person in front of me which foot should be used to jump with?
Needless to say the indecision just before the jump made him fail to perform the jump.

ETA Right & Left are relative constraints and are meaningless when used in an absolute sense. Yet they are regularly used as an absolute trait. Same is true/false for right/wrong.

If the North-Pole of a magnet is attracted to the South-Poles of other magnets, which Pole is the the North-Pole of the magnet in a compass attracted to?
