It is clear that someone found a trick for fast mining. I kind of happen to know what might be...

Is it IntelliHash?   Shocked

Last 3 blocks mined within 1 minute.
Huh 10 minutes, actually.

I thought I posted by the times indicated by blockchain.info at the time. Note that timestamps are malleable and timestamps of reception by blockchain.info don't seem to be accurate. Block timestamp and blockchain.info timestamp for reception are not in chronological order for blocks 354642 and 354643 (this is not strange and happens quite often). Malleability of blocks timestamps may explain this fact but not timestamp of reception by blockchain.info (that may just copy the block timestamp).

All 4 nounces very close by.
Not close at all. A difference 300,000 is about one thirteenth of the maximum range, which means consecutive nonces will be this close together over 10 times a day.

4Byte nounce is between 1 and 2^32-1=4.294.967.295 right? Where is your 300.000 being 1/13th coming from?

All 4 blocks with a length of 731 kB
Which happens to be just under 750 metric kilobytes, which is the default maximum block size.

Nobody has found a trick for fast mining, that's just good luck. Sometimes it can be an hour or two between blocks, other times it can just be seconds between them.

Please, compute the probability of having the same length within 1kB,

Miners decide the size of their blocks. It is not a random process. And only 3 out of 4 of your linked blocks are 731kb, and it is not rare: http://www.reddit.com/r/Buttcoin/comments/2sezuu/is_there_a_reason_a_lot_of_blocks_are_731x_kb/

There is nothing odd going on here.  There is no "pre-mine" or some "trick for fast mining".  It is like seeing a dog in the clouds.  There isn't really a dog here.

Look at the last 4 blocks:

Block 354644; https://blockchain.info/es/block/00000000000000000d35454365c161addc0146286bcd6839017baffe75a2c3e9

There is nothing unexpected by this, while it is indeed rare, (different)rare events happen all the time.

First of all those 4 are not found by the same address, second look at the places where they supposed to be found.
This happens ofcourse not often but it happens that some people get shortly after another some blocks.
They seldom fall at the same spot but as you can see 2 are at the same spot and the 2 earlier ones elsewhere.
So for as i can see does it look so special

Remember, mining has changed. ITs more centralized.. Did one person or one machine find those four blocks. i guess its hard to say anymore.. people that mine usually have tens or hundred of terabytes of power.. Soon, you will need hundreds of petahashes to find a block, lol... I have mixed feelings when bitcoin price took off. It made me a tidy sum, yet it made it so mining wasn't profitable for me. So, i think I probably lost money. it brought rich people out of the wood work to mine that would have never mined had bitcoin stayed at the 10 to 15 dollar level. too many cooks in the kitchen... When I was doing the math to figure out if spending 30k on a mining rig was worth it back in the day, the most I thought bitcoin could go up in the 4 years that i did the math was about 50 dollars a coin and I thought it would stay sub 20 dolllars for years. so, I was way off, lol..

You are not addressing the point.

Please, compute the probability of having the same length within 1kB, the probability of mining three blocks within 1 min, and the probability of having nearby nounce.

Then multiply since these events are independent.
