Another base58 question.

[Coherent1337]

Hello everyone.

So,                 0x39 =  0011 1001 = 57 is a "z"      in base58.
But why is        0x3A = 0011 1010 = 58 a "21"        in base58?

And what is the difference between base58 and base58check and where exactly is base58check used?

Thanks

Hm okay. but why is 58 21 and not "Q"? And on what does it depend of 57 is P or Q?
