Advanced Encryption Standard Algorithm Keysize limit How does the key schedule of Rijndael looks for keysizes other than 128 bit?

It said in wikipediain Wikipedia that "The blocksize has a maximum of 256 bits, but the keysize has no theoretical maximum":

[....] Rijndael can be specified with block and key sizes in any multiple of 32 bits, with a minimum of 128 bits. The blocksize has a maximum of 256 bits, but the keysize has no theoretical maximum.

How can I create awould the key schedule if mylook for these other key is 136 bits? I'm confused with this, because I thoughtsizes, I can limit thelike a 136-bit key in 16 characters long equals to 128 bits...?

How would the key schedule look for these other key sizes, like a 136-bit key?
