Strange behavior of small OP_RETURN outputs

I'm hoping someone familiar with the structure of an OP_RETURN output can help point me to a technical resource or help explain some strange behavior I've noticed in OP_RETURN outputs that are 4 bytes or smaller. It seems that data 4 bytes or less doesn't get pushed onto the stack in the same manner as outputs with 5-80 bytes.

For example, bitcoin txid 71a5e4e683b06b1b2accdab265abfad8335d75f3d5436e7435d0e48a33f283bb has an OP_RETURN output that looks like this:

 [vout] => Array ( [0] => Array ( [value] => 0 [n] => 0 [scriptPubKey] => Array ( [asm] => OP_RETURN 24897 [hex] => 6a024161 [type] => nulldata ) ) 

The OP_RETURN hex value of 6a024161 should have scripted with the OP_RETURN (6a) pushing 2 bytes of data (02) to the stack, with the data being 4161. Yet the data that was actually pushed is 24897. This doesn't appear consistent with the script specification (https://en.bitcoin.it/wiki/Script). I've been able to consistently reproduce these results by building transactions with bitcoin core, and once the data is 5 bytes or larger it behaves consistent with the specification. Does anyone know what's going on here or have any information they can share on this?

Thanks!

Do you keep coins in exchange's wallet or in personal hardware/software wallet and transfer back and forth to exchange?

I trade couple of times each month in Binance.

Many people say it's not safe to keep coins in exchange's wallet.

But I've got some friends do that since they don't bother transferring all the time when trading.

​

What do you guys do and think?

American lawmakers push Facebook to drop Libra and adopt Bitcoin instead

I may be wrong but I believe Libra Coin is just a Bluff to test and see what peoples reaction to it will be when in reality Facebook will use Bitcoin instead. The 18th Million Bitcoin will be mined Tomorrow. I am a Bitcoin Fanatic and proud to be invested in it Long term. I feel sorry for the friends and Family who I tried to convince to buy and HODL Bitcoin. I recommend to everyone to at least own as Much BITCOIN as possible before owning any other coin. May the Force be with us. Salute
